Segal-Bargmann transform for generalized partial-slice monogenic functions

Zhenghua Xu, Irene Sabadini

The concept of generalized partial-slice monogenic functions has been recently introduced to include the two theories of monogenic functions and of slice monogenic functions over C…

An introduction to the fine structures on the -spectrum

Fabrizio Colombo, Antonino De Martino, Stefano Pinton +2

Holomorphic functions are fundamental in operator theory and their Cauchy formula is a crucial tool for defining functions of operators. The Fueter-Sce extension theorem (often cal…

Bergman kernels for monogenic and contragenic functions in the interior and exterior of a sphere

R. García-Ancona, J. Morais, R. Michael Porter

Contragenic functions are defined to be reduced-quaternion-valued harmonic functions which are orthogonal to all monogenic and antimonogenic functions in the norm of a given…

Domains of existence of slice regular functions in one quaternionic variable

Xinyuan Dou, Ming Jin, Guangbin Ren +1

Recently, we introduced domains of slice regularity in the space of quaternions and also proved that domains of slice regularity satisfy a symmetry with respect to pat…
