Let () be a sequence of linear operators on the Banach space X.Consider the statement that () converges to some operator T on X.This could have several different meanings: If ‖ ‖, that is, the operator norm of (the supremum of ‖ ‖, where x ranges over the unit ball in X) converges to 0, we say that in the uniform operator topology.

Understanding the definition of Uniform Absolute Convergence

In mathematical analysis, the uniform norm (or sup norm) assigns to real- or complex-valued bounded functions defined on a set the non-negative number This norm is also called the supremum norm, the Chebyshev norm, the infinity norm, or, when the supremum is in fact the maximum, the max norm.
