WebJan 1, 1986 · The notion of cryptomorphism was introduced by G. Birkhoff for algebras.

In mathematics, two objects, especially systems of axioms or semantics for them, are called cryptomorphic if they are equivalent but not obviously equivalent. In particular, two definitions or axiomatizations of the same object are "cryptomorphic" if it is not obvious that they define the same object. Examples of … See more The word was coined by Garrett Birkhoff before 1967, for use in the third edition of his book Lattice Theory. Birkhoff did not give it a formal definition, though others working in the field have made some attempts since. See more • Combinatorial class, an equivalence among combinatorial enumeration problems hinting at the existence of a cryptomorphism See more Its informal sense was popularized (and greatly expanded in scope) by Gian-Carlo Rota in the context of matroid theory: there are dozens of equivalent axiomatic approaches to matroids, but two different systems of axioms often look very different.

WebI would say that the existence of cryptomorphisms is a sign of the richness and naturality of a mathematical concept -- it means that it has an existence which is independent of any particular way of thinking about it -- but that on the other hand the existence of not obviously equivalent cryptomorphisms tends to make things more complicated, not … city chic delivery times nzWebApr 6, 2024 · My intention is to explicit describe the cryptomorphism by means of a bijection between the set system of the feasible sets of the greedoid and the "closure" operator. dict 1 2 3 : user 能创建一个字典WebCryptomorphism definition: (mathematics) The condition of being cryptomorphic. . city chic dinner date dressWebMar 1, 2024 · Cryptomorphisms between the rank, independence and bases axioms were already proven in [9].For independence and bases, it turns out there is an extra axiom needed in addition to the classical case: simply taking a straightforward q-analogue of the classical axioms is sometimes insufficient to find axioms for a q-matroid.A cryptomorphism … dict2stringWebcryptomorphic adjective Two objects, especially systems of axioms or semantics for them, are called cryptomorphic if they are equivalent (possibly in some informal sense) but not obviously equivalent.
