Matrix functions preserving sets of generalized nonnegative matrices
... 2. Matrix functions preserving PFn. In this section, we completely characterize matrix functions preserving the set of real n × n eventually positive matrices, PFn. For n = 1, these functions are simply functions f which are holomorphic on an open set Ω ⊆ C containing the positive real axis and whic ...
