Hello all, The next MaPSS talk of this semester will be at 17:00 on Mon 14th of October in Carslaw 535. It’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of course get some free pizza! ************************************************************************************** Speaker: Timothy Collier Title: Existence of mild solutions for accretive operators Abstract: Partial differential equations have a number of different notions of solutions in part due to the variety of methods constructed to obtain results of existence, uniqueness and regularity. In this talk I will introduce the analysis of PDEs including one such notion well suited to evolution equations, namely mild solutions. In understanding these we will see the importance of accretive operators such as the negative Laplacian for which we can obtain mild solutions. We will then see some relationships between this and other notions of solutions. ************************************************************************************** See you there!
