Title: Structure breaking by homogenization.
Abstract: In this talk, we will give an alternate (and constructive) proof
to a result of Luc Tartar which demonstrated the loss of semi-group
structure due to the presence of high frequency oscillations in
coefficients. The discussions will revolve around
(i) the notion of weak convergence in Lp spaces;
(ii) the notion of two-scale convergence in the theory of homogenization.
Furthermore, we shall discuss some interesting results in the context of
(i) structure breaking in other differential equations;
(ii) inverse homogenization.
We also intend to list some related open problems which are accessible to
available techniques.
