Congratulations to Dr. Bulent Tosun on the acceptance of his joint paper, “Knotted solid tori in contact manifolds,” for publication in the Proceedings of the National Academy of Sciences. Widely regarded as one of the world’s premier multidisciplinary research journals, PNAS is exceptionally selective and is considered alongside Nature and Science among the most prestigious venues for scientific research.

We are pleased to announce that Troy Roberts from Washington University St. Louis and former UA student will be giving a Analysis Seminar talk today at 11:00 AM in GP 346 . Please see below for title and abstract.

Title: Testing Theorems and Matrix Weights

Abstract: To show that an operator T from X to Y is bounded, one typically must compute the norm of Tx for all unit vectors x in X. Testing theorems tell you that in certain cases it is enough to compute the norm of Tx for all vectors in a "nice" subclass of X. This approach proved very useful in studying the two-weight problem, i.e., when operators are bounded from L^p(w) to L^p(v) for two different weights w and v.

We will discuss results of this type with particular emphasis on the well-localized operators introduced by Nazarov, Treil, and Volberg. We will also talk about our efforts to generalize these results to the matrix weight setting when p is not 2 and discuss some of the difficulties that arise.

We are pleased to announce that Cody Stockdale from Clemson University will be giving a talk 4/29/26 at 11:00 AM in GP 346 . Please see below for title and abstract.

Title: Sharp weighted weak-type bounds for operators

Abstract: The area of weighted norm inequalities has been at the forefront of harmonic analysis since the seminal work of Muckenhoupt et al. in the 1970s. More recently, researchers have sought sharp bounds with respect to A_p weight characteristics. We discuss new quantitative weak-type bounds for operators in harmonic and complex analysis.

Hope to see you there!
