Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".

Calculation of complex polygamma functions. (Japanese) Zbl 0861.33016
This paper provides a computer program which enables to calculate complex polygamma functions for complex arguments accurately. The basic part of this program is calculated as combinations of power series based on expansions with Riemann zeta functions. Relative errors in the computation of either real functions or complex functions are less than 1·11×10 -16 .
