A note on the diamond operator

Research output: Contribution to journalArticlepeer-review

Abstract

We show that if 1 â W F and F â F â W F, then F â- â W F, where â and â- are the following operations in the Weihrauch lattice: â is the compositional product, which allows the use of two principles in sequence, while the diamond operator â- allows an arbitrary but finite number of uses of the given principle in sequence. This answers a question of Pauly.
