Estimates of Norms on Krein Spaces

TL;DR

This paper discusses various norms on Krein spaces, providing estimates and generalizing some existing results to better understand their properties.

Contribution

It introduces new estimates of norms on Krein spaces and generalizes results from Bognar's work.

Findings

Provides bounds for norms on Krein spaces

Generalizes previous results in the literature

Enhances understanding of Krein space structure

Abstract

Various norms can be defined on a Krein space by choosing different underlying fundamental decompositions. Some estimates of norms on Krein spaces are discussed and few results in Bognar's paper are generalized.
