Cryptomorphism

WebThe word cryptomorphism is not so much a generalization of as a riff on "isomorphism": "cryptomorphism" is what you get when you mash "crypto" and "isomorphism". Two things are cryptomorphic if they're "secretly" the "same shape": that is, if it's "difficult to see" that they're the same. WebCryptomorphism (i.e. matroids have a million di erent de nitions.)

WebMar 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. WebIn mathematics, two objects, especially systems of axioms or semantics for them, are called cryptomorphic if they are equivalent but not obviously equivalent. This word is a play on the many morphisms in mathematics, but "cryptomorphism" is only very distantly related to "isomorphism", "homomorphism", or "morphisms".The equivalence may possibly be in … how much money is 1000 pounds in us money https://jcjacksonconsulting.com

WebFirst, we extend the theory of q-matroids to include a new cryptomorphism, namely that between flats and the rank function. We apply this cryptomorphism to obtain the first examples of q-PMDs; in particular we show that q-Steiner systems are q-PMDs.

WebJan 1, 1986 · Publisher Summary. This chapter discusses cryptomorphisms of non-indexed algebras and relational systems. For universal algebras of a fixed type, there exists a sufficiently well-developed theory. In the abstract Galois theory for operations and relations, which goes back to M. Krasner, there are also many connections between non-indexed ... 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.

Webpolymorphism, in biology, a discontinuous genetic variation resulting in the occurrence of several different forms or types of individuals among the members of a single species. A discontinuous genetic variation divides the individuals of a population into two or more sharply distinct forms.
