DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ags/6/">Non-
 homogeneous T(1) theorem for singular integrals on product quasimetric spa
 ces</a>\nby Trang Thi Thien Nguyen (University of South Australia) as part
  of Analysis and Geometry Seminar\n\n\nAbstract\nIn the Calderón-Zygmund 
 Theory of singular integrals\, the T(1) theorem of David and Journé is on
 e of the most celebrated theorems. It gives easily-checked criteria for a 
 singular integral operator T to be bounded from L^2(R^n) to L^2(R^n). Sinc
 e then\, this classical result has been generalized to various settings\, 
 including replacing the underlying space R^n on which the operators act. \
 nIn this talk\, I will present our work on generalizing the T(1) theorem\,
  that brings together three attributes: 'product space'\, 'quasimetric' an
 d 'non-doubling measure'. Specifically\, we prove a T(1) theorem that can 
 be applied to operators acting on product spaces equipped with a quasimetr
 ic and an upper doubling measure\, which only satisfies an upper control o
 n the size of balls.\n
