Cauchy problems for discrete holomorphic functions
- 2021
-
In: Complex Analysis and Operator Theory. - : Springer Science and Business Media LLC. - 1661-8254 .- 1661-8262. ; 15:1
-
Journal article (peer-reviewed)abstract
- We solve Cauchy problems for discrete holomorphic functions defined on the Gaussian integers, which leads to the existence of discrete holomorphic functions with arbitrarily fast growth. This proves that certain classes of functions are closed in the sense of mathematical morphology.

Book chapter (peer-reviewed)abstract
- We study difficulties that appear when well-established def-initions and results in Euclidean geometry, especially in the theory ofconvex sets and functions in vector spaces, are translated into a discretesetting. Solutions to these problems are sketched.
