Homomorphism obstructions for satellite maps [PDF]
Transactions of the American Mathematical Society. Series B, 2019 A knot in a solid torus defines a map on the set of (smooth or topological) concordance classes of knots in S 3 S^3 . This set admits a group structure, but a conjecture of Hedden suggests that satellite maps never induce interesting ...

THE RELATIVE WEAK ASYMPTOTIC HOMOMORPHISM PROPERTY FOR INCLUSIONS OF FINITE VON NEUMANN ALGEBRAS [PDF]
, 2010 A triple of finite von Neumann algebras B ⊆ N ⊆ M is said to have the relative weak asymptotic homomorphism property if there exists a net of unitary operators {uλ}λ∈Λ in B such that for all x,y ∈ M.

A homomorphism between link and XXZ modules over the periodic Temperley–Lieb algebra [PDF]
, 2012 We study finite loop models on a lattice wrapped around a cylinder. A section of the cylinder has N sites. We use a family of link modules over the periodic Temperley–Lieb algebra E PTL N(β,α)?> introduced by Martin and Saleur, and Graham and Lehrer ...

On finite reflexive homomorphism-homogeneous binary relational systems [PDF]
Discrete Mathematics, 2009 A structure is called homogeneous if every isomorphism between finitely induced substructures of the structure extends to an automorphism of the structure. Recently, P.?J.?Cameron and J.?Nesetřil introduced a relaxed version of homogeneity: we say that a

Representation Homology, Lie Algebra Cohomology and Derived Harish-Chandra Homomorphism [PDF]
, 2014 We study the derived representation scheme DRep_n(A) parametrizing the n-dimensional representations of an associative algebra A over a field of characteristic zero. We show that the homology of DRep_n(A) is isomorphic to the Chevalley-Eilenberg homology

THE NONLINEAR MASLOV INDEX AND THE CALABI HOMOMORPHISM [PDF]
, 2006 In this paper, we find that the asymptotic nonlinear Maslov index defined on the universal cover of the group of all contact Hamiltonian diffeomorphisms of the standard (2n - 1)-dimensional contact sphere is a quasimorphism. Then we show our main result:

Isomorphism between the R-matrix and Drinfeld presentations of quantum affine algebra: Type C [PDF]
Journal of Mathematics and Physics, 2019 An explicit isomorphism between the R-matrix and Drinfeld presentations of the quantum affine algebra in type A was given by Ding and Frenkel [Commun. Math. Phys. 156, 277–300 (1993)].

Density of C-4-critical signed graphs [PDF]
J. Comb. Theory B, 2020 A signed bipartite (simple) graph (G, σ) is said to be C −4-critical if it admits no homomorphism to C −4 (a negative 4-cycle) but every proper subgraph of it does.

A probabilistic public key encryption switching scheme for secure cloud storage
International journal of information technology, 2022 The high demand for user-centric applications such as secure cloud storage laid the foundation for the development of user-centric security schemes with multiple security features in recent years.

Cosets of affine vertex algebras inside larger structures [PDF]
Journal of Algebra, 2014 Given a finite-dimensional reductive Lie algebra g equipped with a nondegenerate, invariant, symmetric bilinear form B, let V k ( g , B ) denote the universal affine vertex algebra associated to g and B at level k.
