(linear algebra) (Of a matrix) which commutes with its conjugate transpose. (functional analysis) (Of a Hilbert space operator) which commutes with its adjoint. (category theory) (Of an epimorphism) which is the cokernel of some morphism. ...
For continuous size-structured harvesting, problem duality and adjoint equations are applied for proving the existence of the bang-bang control in [6,8]. In this work, we apply the Lagrange method and give a recipe to systematically define the adjoint state equations and gradient information. We...
