Hessian Estimates for the Lagrangian mean curvature equation
In this talk, we will derive a priori interior Hessian estimates for the Lagrangian mean curvature equation under certain natural restrictions on the Lagrangian phase. As an application, we will use these estimates to solve the Dirichlet problem for the Lagrangian mean curvature equation with continuous boundary data on a uniformly convex, bounded [Read More...]

The-time dependent thin obstacle problem for the weighted bi-Laplacian
Time dependent equations associated with fourth order operators are used to model many physical phenomena such as plane flame propagation, and phase turbulence in reaction-diffusion systems. They also appears in thin film theory to model long waves on a viscous fluid. We will present our work on a time dependent thin obstacle problem associated with the [Read More...]

Regularity of edges in image processing
Edge detection is an image processing technique for finding the boundaries of objects within images. The Mumford-Shah functional was introduced by Mumford and Shah in 1989 as a variational model for image reconstruction. The most important regularity problem is the famous Mumford-Shah conjecture, which states that (in 2 dimensions) the closure of the jump [Read More...]

Boundedness of commutators on weighted Hardy and BMO spaces
It is know that boundedness of the commutator $[b,H]$ on weighted $L^p$ spaces for $1< p< \infty$ is characterized by $b$ being in a certain BMO space adapted to the given weights. In this talk, we present the case $p=1$ and discuss the space that characterizes boundedness of $[b,H]$ on the weighted Hardy space $H^1(w)$ for certain $Ap$ [Read More...]

Logarithmic Sobolev inequalities on non-isotropic Heisenberg groups
We study logarithmic Sobolev inequalities with respect to a heat kernel measure on finite-dimensional and infinite-dimensional Heisenberg groups. Such a group is the simplest non-trivial example of a sub-Riemannian manifold. First we consider logarithmic Sobolev inequalities on non-isotropic Heisenberg groups. These inequalities are considered with respect [Read More...]

Boundary Homogenization of Planes with Partially-Absorbing Patches
We investigate the capture dynamics of a Brownian particle in half-space above a reflecting plane with a periodic array of partially-absorbing patches. Prior work in this area has considered a reflecting surfaces with fully-absorbing disks. We do this via a hybrid numerical-asymptotic approach, performing matched asymptotic analysis on the survival [Read More...]

Improving and Maximal Inequalitites for Primes in Progressions
Assume that $ y < N$ are integers, and that $(b,y) =1$. Define an average along the primes in a progression of diameter $y$, given by integer $b$. $$A_{N,y,b} := \frac{\phi (y)}{N} \sum_{\substack{n < N\\n\equiv b\mod y}} \Lambda (n) f(x-n),$$ where $\Lambda$ is the von Mangoldt function and $\phi$ is the totient function. We establish improving and [Read More...]

Metalenses and Phase Discontinuity Functions
Metalenses are ultra thin surfaces that are composed of nano structures to focus light. These nano structures manipulate light waves by abrupt phase shifts over the scale of the wavelength to bend them in unusual ways. Compared to the bulky, thick shapes of the conventional lenses, metalenses offer many advantages in optical applications due to their reduced [Read More...]

The Korányi Spherical Maximal Function on Heisenberg groups
In this talk, we will consider the problem of obtaining sharp (up to endpoints) $L^p\to L^q$ estimates for the local maximal operator associated with averaging over dilates of the Korányi sphere on Heisenberg groups. This is a codimension one surface compatible with the non-isotropic Heisenberg dilation structure. I will describe the main features of the [Read More...]

Maximal and minimal weak solutions for elliptic problems with nonlinearity on the boundary
We consider the existence of weak solutions for semilinear elliptic equation with nonlinearity on the boundary. We establish the existence of a maximal and a minimal weak solution between an ordered pair of sub- and supersolution. To prove the result, we utilize the surjectivity of a pseudomonotone and coercive operator, Zorn's lemma and a version of [Read More...]

Overlaps of a spherical spin glass model with an external field
The focus of this talk will be the 2-spin spherical Sherrington Kirkpatrick (SSK) spin glass model with an external field. More specifically, I will discuss the transition between this model and the one without an external field. The talk will provide a brief introduction to the SSK model, focusing on the distribution of spins and how that distribution [Read More...]

Reconstruction of the Shape and Boundary Condition in Inverse Scattering for an Obstacle with Partial Generalized Impedance Boundary
We consider the inverse problem of recovering the shape and boundary coefficients of an obstacle from far field measurements of the scattered field. More specifically the scatterer is impenetrable with Dirichlet boundary condition on a part of its boundary and anisotropic generalized impedance boundary condition on the complementary boundary. The latter is [Read More...]
