Homeomorphisms,In at least some formulations, particularly those inspired by Felix Klein, the central notion of topology is that of a homeomorphism. (Since doughnuts are homeomorphic to coffee cups, topologists are sometimes suspected of not being able to tell the difference.) We turn now to some applications of homeomorphisms within logic.anesthesia 发表于 2025-3-23 20:04:13

Truth Functions,After some philosophical preliminaries, we offer a theory of propositional connectives or truth functions that applies readily to a variety of truth bearers. (By a “truth bearer,” we just mean something that is either true or false.)Concrete 发表于 2025-3-24 05:39:16

Wolfgang U. Eckart,Philipp Ostene elements has a greatest lower and least upper bound. If <S,C> is a C-closure space, then <C,⊂> is a complete lattice in which ∩W is the greatest lower and Cl(UW) is the least upper bound of each subset W of C. It is convenient to let ‘. W’ and ‘(A.B)’ designate Cl(∪ W) and Cl(A∪B), respectively. (完成才能战胜 发表于 2025-3-25 02:06:01
