A new computation of the Bergman kernel and related techniques
We introduce a technique for obtaining the Bergman kernel on certain Hartogs domains. To do so, we apply a differential operator to a known kernel function on a domain in lower dimensional space. We rediscover some known results and we obtain new explicit formulas. Using these formulas, we analyze the boundary behavior of the kernel function on the diagonal. Our technique also leads us to results about a cancellation of singularities for generalized hypergeometric functions and weighted Bergman kernels. Finally, we give an alternative approach to obtain explicit bases for complex harmonic homogeneous polynomial spaces
Zero products of Toeplitz operators on Reinhardt domains
Let be a bounded Reinhardt domain in and
be finite sums of bounded quasi-homogeneous functions.
We show that if the product of Toeplitz operators on the Bergman space on , then for some .Comment: to appear in Can. Math. Bull., 11 page
A B\'{e}koll\`{e}-Bonami Class of Weights for Certain Pseudoconvex Domains
We prove the weighted regularity of the ordinary Bergman projection on
certain pseudoconvex domains where the weight belongs to an appropriate
generalization of the B\'{e}koll\`{e}-Bonami class. The main tools used are
estimates on the Bergman kernel obtained by McNeal and B\'{e}koll\`{e}'s
original approach of proving a good-lambda inequality.Comment: 24 page
Bekoll\'e-Bonami estimates on some pseudoconvex domains
We establish a weighted norm estimate for the Bergman projection for a
class of pseudoconvex domains. We obtain an upper bound for the weighted
norm when the domain is, for example, a bounded smooth strictly pseudoconvex
domain, a pseudoconvex domain of finite type in , a convex domain
of finite type in , or a decoupled domain of finite type in
. The upper bound is related to the Bekoll\'e-Bonami constant and
is sharp. When the domain is smooth, bounded, and strictly pseudoconvex, we
also obtain a lower bound for the weighted norm.Comment: 28 pages. An application to the weak-type estimate is added as a new
