A multispecies totally asymmetric zero range process and Macdonald polynomials Prof. Arvind Ayyer, IISc
Macdonald polynomials are a remarkable family of symmetric functions that are known to have connections to combinatorics, algebraic geometry, and representation theory. Due to the work of Corteel, Mandelshtam and Williams, it is known that they are related to the asymmetric simple exclusion process (ASEP) on a ring.The modified Macdonald polynomials are obtained from the Macdonald polynomials using an operation called plethysm.In this talk, Prof. Arvind answered the question, ‘Are modified Macdonald polynomials related to some other particle system?’ in the affirmative via a multispecies totally asymmetric zero-range process (TAZRP). He also presented a Markov process on tableaux that projected to the TAZRP, derived formulas for stationary probabilities and certain correlations, and proved a remarkable symmetry property for local correlations.

Divergence-free methods for hyperbolic PDEs Prof. Praveen C (TIFR CAM, Bengaluru)
Prof. Praveen explained why many hyperbolic PDE problems like Maxwell's equations governing electromagnetic waves and MHD approximation for plasma contain an intrinsic constraint on the divergence of some vector field likemagnetic field. He stated why standard numerical methods may not respect such constraints which can lead to inaccurate or totally wrong solutions, or make the methods unstable. In his talk, Prof. Praveen explained why special techniques are needed to ensure approximate or exact preservation of these constraints and presented some ideas for exactly divergence-free methods based on discontinuous Galerkin framework.

Prime-characteristic commutative algebra
Dr. Manoj Kummini, CMI This expository talk by Dr. Manoj Kummini focussed on the Ring theory and explained how every commutative ring of prime characteristic $p$ has the Frobenius endomorphism $F : r \mapsto r^p$. This, he said, can be used to study singularities of (the prime spectra of) such rings. In this session, Dr. Manoj described a class of such singularities, called F-rational rings, a notion closely related to rational singularities over complex numbers.

Finite Element Computations of Free surface and Multiphase flows with Surfactants
Dr. Sashikumaar Ganesan, Dept. of Computational and Data Sciences, IISc Bangalore Dr. Sashikumaar Ganesan in this talk explained why computations of free surface and two-phase flows are very challenging, in particular, when surface-active agents (surfactants) are present in the fluid. He went on to describe how Marangoni forces are induced and how the existence of surfactants in fluids strongly influences the dynamics of the flow.

Semiglobal optimal Feedback stabilization of autonomous systems via deep neural network approximation
Dr. Karl Kunisch (RICAM, Linz & Uni Graz, Austria) The presentation explored the joint work of Dr.Karl Kunisch and his research team with Dr. Daniel Walker. This collaborative research analysed a learning approach for optimal feedback gains for nonlinear continuous time control systems. The goal of the study was to establish a rigorous framework for computing approximating optimal feedback gains using neural networks. Dr. Karl explained how the approach rests on two main ingredients. First, an optimal control formulation involving an ensemble of trajectories with 'control' variables given by the feedback gain functions. Second, an approximation to the feedback functions via realizations of neural networks. Based on universal approximation properties they proved the existence and convergence of optimal stabilizing neural network feedback controllers.

First and second order shape optimization based on restricted mesh deformations
Dr. Roland Herzog (TU Chemnitz, Germany) Dr. Roland Herzog explained how in shape optimization problems involving partial differential equations, the domain is often represented by a computational mesh, and the optimization proceeds by repeatedly updating the mesh node positions. It is well known that such a procedure eventually may lead to a deterioration of mesh quality, or even an invalidation of the mesh, when interior nodes penetrate neighbouring cells. Dr. Roland examined this phenomenon, which can be traced back to the ineptness of the discretized objective when considered over the space of mesh node positions. As a remedy, they proposed a restriction in the admissible mesh deformations, inspired by the Hadamard structure theorem. First and second order methods were considered in this setting. Numerical results showed that mesh degeneracy can be overcome, avoiding the need for remeshing or other strategies.

Modelling of biochemical processes with randomness
Lecture series by Prof. Erika Hausenblas, Montanuniversitst Leoben, Austria Prof. Erika Hausenblas delivered a series of 4 lectures during her visit to IISER TVM. Dr. Erika has observed that chemical and biochemical reactions can exhibit surprisingly different behaviours, from multiple steady-state solutions to oscillatory solutions and chaotic behaviours. Such behaviours have been of great interest to researchers for many decades. The Briggs-Rauscher, Belousov-Zhabotinskii and Bray-Liebhafsky reactions, for which periodic variations in concentrations can be visualized by changes in colour, are experimental examples of oscillating behaviour in chemical systems. In the series of lectures, some systems of stochastic reaction-diffusion processes were introduced, the existence and uniqueness of solution were tackled, and finally some results related to numerical modelling were presented.

NCM Workshop on Complex Fluids and Liquid Crystals
Research in materials and complex fluids has witnessed unprecedented growth in recent years with the advent of metamaterials, nano-materials, biomaterials, polymers, microfluidics, smart fluids etc. In particular, soft materials that are intermediate in character between conventional solids and liquids, have attracted huge academic interest and in fact, several soft materials are also classified as complex fluids with unusual mechanical, optical and rheological properties. Nematic liquid crystals are paradigm examples of soft materials and complex fluids. Nematics combine the fluidity of liquids with the orientational order of conventional solids. Consequently, they have a direction-dependent response to external fields and light, making them the working material of choice for the multi-billion liquid crystal display industry, along with new applications in microfluidics, smart devices, photonics, actuators etc. Four faculty members from the University of Strathclyde, and one faculty member each from IISER TVM and IIT Bombay delivered 4 lectures on specific topics to complete the 10-day workshop.

NCM Workshop on Numerical Methods for Partial Differential Equations
This workshop was intended for Ph. D. scholars and Postdocs to learn new techniques and use them in their research. Partial Differential Equations(PDEs) play an important role in science and engineering applications, such as the propagation of heat or sound, fluid flow, finite elasticity, electrodynamics, cancer modeling, etc. In general, the solution of PDEs can be very challenging, depending on the type of equation, the number of independent variables, the boundary and initial conditions, and nonlinearities. This workshop offered an introduction to some important numerical methods for linear and non-linear ordinary and partial differential equations, and various numerical discretization techniques like, finite difference (FDM), finite volume methods (FVM),finite element methods (FEM), and discontinuous Galerkin methods (DGM), for their solution. It also included an introduction to Machine Learning, Deep Learning, and Physics Informed Neural Networks (PINNs).
Outreach Programs (CMIT)
September 18, 2022
Outreach Program of the Club of Mathematics IISER TVM (CMIT)
A one-day outreach program was organized by the CMIT for school students of classes 8 to 12 from schools around the Institute and from the city of Thiruvananthapuram. The primary intent of the program was to give school children an opportunity to visit the IISER TVM campus and allow them to explore the exciting world of mathematical research and its application in everyday life. A number of competitions and programs were organized including a rangoli competition, talks by students, and a quiz competition. Certificates and prizes were awarded to the winners of the competitions.
