For a positive and invertible linear operator T acting on a C ⋆ -algebra, we give necessary and sufficient criteria for the inverse operator T − 1 to be positive, too. Moreover, a simple counterexample shows that T − 1 need not be positive even if T is unital and its spectrum is contained in the unit circle.

There is a mistake in the proof of Theorem 3 of “A matricial view of the Collatz conjecture” [1] that can not be rectified. As such, a revised statement and proof of Theorem 3 is presented.

P-polynomial and bipartite coherent configurations

Linear Algebra and Its Applications
Sabrina Lato

We introduce the notion of P-polynomial coherent configurations and show that they can have at most two fibers. We then introduce a class of two-fiber coherent configurations which have two distinguished bases for the coherent algebra, similar to the Bose-Mesner algebra of an association scheme. Examples of these bipartite coherent configurations include the P-polynomial class of distance-biregular graphs, as well as quasi-symmetric designs and strongly regular designs.
