A theory on M-matrices is derived from simple results on inverse-positive linear operators. Some applications to eigenvalue theory and iterative procedures are discussed. The concepts occurring in ...

The 34th International Workshop on Operator Theory and is Applications (IWOTA 2023) takes place at the University of Helsinki from July 31 through August 4, 2023. The program consists of approximately ...
