  • Best approximations, distance formulas and orthogonality in C{*}-algebras
    Grover, Priyanka ; Singla, Sushil
    For a unital C{*}-algebra A and a subspace B of A, a characterization for a best approximation to an element of A in B is obtained. As an application, a formula for the distance of an element of A ... from B has been obtained, when a best approximation of that element to B exists. Further, a characterization for Birkhoff-James orthogonality of an element of a Hilbert C{*}-module to a subspace is obtained.
