IDA and Hankel operators on Fock spaces
Zhangjian Hu, Jani A. Virtanen
We introduce a new space IDA of locally integrable functions whose integral distance to holomorphic functions is finite, and use it to completely characterize boundedness and compa…
Fredholm Toeplitz operators on doubling Fock spaces
Zhangjian Hu, Jani A. Virtanen
Recently the authors characterized the Fredholmn properties of Toeplitz operators on weighted Fock spaces when the Laplacian of the weight function is bounded below and above. In t…
On the exponential integrability of conjugate functions
H. Gissy, S. Miihkinen, J. A. Virtanen
We relate the exponential integrability of the conjugate function to the size of the gap in the essential range of . Our main result complements a related theorem of…
Weak BMO and Toeplitz operators on Bergman spaces
Jari Taskinen, Jani A. Virtanen
Inspired by our previous work on the boundedness of Toeplitz operators, we introduce weak BMO and VMO type conditions, denoted by BWMO and VWMO, respectively, for functions on the…
