1. राघव वर्मा Hermitian Operators To every Hermitian operator , there exists (ATLEAST) one basis consisting of orthogonal eigenvectors, It is diagonal in this eigen basis & has eigen values as its diagonal entries. Before we prove that lets prove another theorem If  |V  = 0 implies |V  = 0 then  -1 exists
