Efficient Approaches for Verifying the Existence and Bound of Inverse of Linear Operators in Hilbert Spaces
Journal of Scientific Computing(2023)
摘要
This paper describes some numerical verification procedures to prove the invertibility of a linear operator in Hilbert spaces and to compute a bound on the norm of its inverse. These approaches improve on previous procedures that use an orthogonal projection of the Hilbert space and its a priori error estimations. Several verified examples which confirm the effectiveness of the new procedures are presented.
