I am looking for various applications of the open mapping theorem (https://en.wikipedia.org/wiki/Open_mapping_theorem_(functional_analysis) ) other than only the closed graph theorem and that if two comparable norms make a space Banach then they are equivalent . Any Journal or Book reference or any links are highly appreciated . Please help . Thanks in advance
