On the concept of discrete convergence
Otto Karma · Numerical Functional Analysis and Optimization · 1992
F. Stummel's notion of discrete approximation and one of its possible concretizations are used. The concepts of consistency, closedness, stability (BR-stability) and regularity (B-regularity) of the sequences of operators at some point v are considered. The behavior of the sequences of the solutions of approximating equations (sequences of o-solutions) is studied.
