Abstract: The theme for this talk will be taken from the famous physicist Randall Munroe: https://xkcd.com/171/
More specifically, we will try to understand how ideas from string theory…
Abstract: I will discuss the travel time tomography problem for the elastic wave equation, where the aim is to recover elastic coefficients in the interior of an elastic medium given the travel times of the corresponding elastic waves. I will consider in particular the transversely…
Abstract: In 1960's Landis conjectured that a nontrivial solution to a time-independent Schrödinger equation with bounded potential cannot decay faster than exponentially. In 1992 the conjecture was disproved by Meshkov, who constructed…
The Fisher-KPP equation was proposed in 1937 as a model for the spread of an advantageous gene through a one-dimensional habitat, such as a shoreline. Since then, remarkably precise information on the location of the traveling front has been achieved through a connection with branching Brownian…
In my last talk, I discussed the Gersten spectral sequence for a finite-dimensional Noetherian scheme, starting from the K-theory of its residue fields and converging to its G-theory, and demonstrated an equivariant analogue. This time, we will take it in a different direction and show that one…
Abstract: In this talk I will discuss and compare two approaches via Fredholm theory to resolvent estimates for the Laplacian of asymptotically conic spaces (such as appropriate metric perturbations of Euclidean space), including in the zero spectral…
A positive integer d is called a congruent number if there exists a right triangle with rational side lengths whose area is d. After giving some…
