Korovkin results and Frobenius optimal approximants for infinite dimensional bounded linear operators
Kiran Kumar, M. N. N. Namboodiri, Stefano Serra-Capizzano
The classical as well as non commutative Korovkin-type theorems deal with convergence of positive linear maps with respect to modes of convergences such as norm convergence and wea…
