When is the frame of nuclei spatial: A new approach
(2020-07-01)For a frame L, let XL be the Esakia space of L. We identify a special subset YL of XL consisting of nuclear points of XL, and prove the following results: • L is spatial iff YL is dense in XL. • If L is spatial, then ... -
The frame of the p-adic numbers and a p-adic Version of the Stone-Weierstrass Theorem in Pointfree Topology
(2020-03-15)The algebraic nature of a frame allows its definition by generators and relations. Joyal used this to introduce the frame of the real numbers and Banaschewski studied this frame with a particular emphasis on the pointfree ... -
