Orthogonality for biadjoints of operators
arXiv:2212.05109
Abstract
In this paper we study Birkhoff-James Orthogonality for biadjoints of operators. We partly solve the problem, if an operator is orthogonal to the space of operators valued in a subspace, when the is the norm of biadjoint is attained at a point where the value is orthogonal to the subspace?
