PhD Thesis colloquium

Title: Homogenization of PDEs on oscillating boundary domains with L1 data and Optimal control problems
Speaker: Renjith T. (IISc Mathematics)
Date: 17 January 2023
Time: 11 am
Venue: LH-1, Mathematics Department

This talk will comprehensively examine the homogenization of partial differential equations (PDEs) and optimal control problems with oscillating coefficients in oscillating domains. We will focus on two specific problems. The first is the homogenization of a second-order elliptic PDE with strong contrasting diffusivity and $L^1$ data in a circular oscillating domain. As the source term we are considering is in $L^1$, we will examine the renormalized solutions. The second problem we will investigate is an optimal control problem governed by a second-order semi-linear PDE in an $n$-dimensional domain with a highly oscillating boundary, where the oscillations occur in $m$ directions, with $1<m<n$. We will explore the asymptotic behavior of this problem by homogenizing the corresponding optimality systems.
