    Proving Unitary Operators = e^iA for Self Adjoint Matrix

    Homework Statement Prove or disprove: if U is in the vector space of complex n x n matrices, then U is unitary if and only if U= e^iA, where A is some self adjoint matrix in same vector space, all of whose eigenvalues lie in the interval [0,2pi) Homework Equations A is self adjoint; A*...
