WebIn operator theory, a bounded operator T: X → Y between normed vector spaces X and Y is said to be a contraction if its operator norm T ≤ 1. This notion is a special case of the concept of a contraction mapping, but every bounded operator becomes a contraction after suitable scaling.The analysis of contractions provides insight into the structure of … WebLast week we motivated the study of strongly continuous semigroups by standard PDE examples.
