    • 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.

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. Dr. Sashikumaar presented a finite-element scheme based on a coupled arbitrary Lagrangian-Eulerian and Lagrangian approach to compute free surface and interface flows with soluble surfactants.

He then went on to explain the Rothe method to prove the existence of weak solutions of the damped Navier-Stokes equations subject to Navierslip boundary condition with nonlinear source term in a bounded domain. The talk ended with a discussion on their future research plans.

    • 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.

    • Prof. Carsten Carstensen, Humboldt-Universitat zu Berlin, Germany.

    • 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.
