TY - JOUR T1 - Spectral Theorem for Compact Self -Adjoint Operator in Γ -Hilbert space AU - Islam, Sahın Injamamul AU - Sarkar, Nırmal AU - Das, Ashoke PY - 2022 DA - March DO - 10.31197/atnaa.877757 JF - Advances in the Theory of Nonlinear Analysis and its Application JO - ATNAA PB - Erdal KARAPINAR WT - DergiPark SN - 2587-2648 SP - 93 EP - 100 VL - 6 IS - 1 LA - en AB - In this article we investigate some basic results of Self-adjoint Operator in Γ-Hilbert space. We proof some similar results on Self-adjoint Operator in this space with some specific norm. Finally we will prove that the Spectral Theorem for Compact Self-adjoint Operator in Γ -Hilbert space and the converse is true.
