227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesMUCKENHOUPT-WHEEDEN CONJECTURES FOR SPARSE OPERATORS Abstract. In this talk, we will show an example of a pair of weights (u, v) for which the Hardy-Littlewood maximal function is bounded from Lp(v) to Lp(u) and from Lp! (u1−p! ) to Lp! (v1−p! ) while a dyadic sparse operator is not bounded on the same domain and

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

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle : Contact geometry in low dimensions Abstract: This series of talks will be about explaining some fundamental open problems in three-dimensional contact geometry. This third talk will be on overtwisted vs. tight dichotomy (or flexible vs. rigid), and existence problem of tight contact structures.

227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle : On polynomial n-tuples of commuting isometries Abstract : We extend some of the results of Agler, Knese, and McCarthy to n-tuples of commuting isometries for n>2. Let V=(V_1,...,V_n) be an n-tuple of a commuting isometries on a Hilbert space and let Ann(V) denote the set of all n-variable polynomials p such that p(V)=0.
