72Nakayama lemma — In mathematics, more specifically modern algebra and commutative algebra, Nakayama s lemma also known as the Krull–Azumaya theorem[1] governs the interaction between the Jacobson radical of a ring (typically a commutative ring) and its finitely… …
73Floer homology — is a mathematical tool used in the study of symplectic geometry and low dimensional topology. First introduced by Andreas Floer in his proof of the Arnold conjecture in symplectic geometry, Floer homology is a novel homology theory arising as an… …
74Fully characteristic subgroup — In mathematics, a subgroup of a group is fully characteristic (or fully invariant) if it is invariant under every endomorphism of the group. That is, any endomorphism of the group takes elements of the subgroup to elements of the subgroup.Every… …
75Eisenstein ideal — In mathematics, the Eisenstein ideal is a certain ideal in the endomorphism ring of the Jacobian variety of a modular curve. It was introduced by Barry Mazur in 1977, in studying the rational points of modular curves. The endomorphism ring in… …
76Group with operators — In abstract algebra, a branch of pure mathematics, the algebraic structure group with operators or Ω group is a group with a set of group endomorphisms.Groups with operators were extensively studied by Emmy Noether and her school in the 1920s.… …
77Torsion tensor — In differential geometry, the notion of torsion is a manner of characterizing a twist or screw of a moving frame around a curve. The torsion of a curve, as it appears in the Frenet Serret formulas, for instance, quantifies the twist of a curve… …
78Cuntz algebra — In C* algebras, the Cuntz algebra (after Joachim Cuntz) is the universal C* algebra generated by n isometries satisfying certain relations. It is the first concrete example of a separable infinite simple C* algebra. Every simple infinite C*… …
79Elementary abelian group — In group theory an elementary abelian group is a finite abelian group, where every nontrivial element has order p where p is a prime.By the classification of finitely generated abelian groups, every elementary abelian group must be of the form:(… …
80Vertex model — A vertex model is a type of statistical mechanics model in which the Boltzmann weights are associated with a vertex in the model (representing an atom or particle). This contrasts with a nearest neighbour model, such as the Ising model, in which… …
