Generalized Lob’s Theorem.Strong Reflection Principles and Large Cardinal Axioms

In this article, a possible generalization of the Lob’s theorem is considered. Main result is: let κ be an inaccessible cardinal,

On a New Summability Result for Operator Matrices

For matrices of quasi-homogeneous operators we establish a summability result which is a useful complement of a recent summability result.

A Unified Convergence Theorem

We prove a unified convergence theorem, which presents, in four equivalentforms, the famous Antosik-Mikusinski theorems. In particular, we show that Swartz' three uniformconvergence principles are all equivalent to the Antosik-Mikusinski theorems.
