228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Dyadic Harmonic Analysis and Weighted Inequalities Abstract: In this talk we will present some basic ideas in harmonic analysis via simpler dyadic models. We will show how they can be used to describe important continuous objects such as the Hilbert transform or more generally singular integral operators. We will introduce the dyadic setting, Haar functions, and basic

In this talk, we will introduce optimal conditions, expressed in terms of Sobolev spaces, on m-linear Fourier multiplier operators to be bounded from a product of Lebesgue or Hardy spaces to Lebesgue spaces. Our results are sharp and cover the bilinear case (m

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle:Contact and symplectic geometry in low dimensions Abstract: This series of talks will be about explaining some fundamental open problems in three-dimensional contact geometry. The first talk will be devoted to a gentle introduction to low dimensional contact and symplectic topology: some of the important problems that have been shaping much of current research, and

227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Fractional Integral Operators Associated to Schrodinger Operators Abstract: Consider the Schroedinger operator Lf(x) = - Laplace f(x) + V(x)f(x). We investigate weighted inequalities for the fractional integral operator I_a = (L)^-a/2. More precisely, let 0 < a < n and 1/p - 1/q = a/n, we would like to estimate the operator norm of

Abstract: We revisit basic nonhomogeneous Caldero´n-Zygmund theory from the point of view of martingales. Given a measure µ of polynomial growth on Rd, we refine a deep result by David and Mattila to construct an
