Simplicial Endomorphisms
A presentation by generators and relations is given for the monoids of endomorphisms in the simplicial category. These monoids are submonoids of monoids one finds in Temperley-Lieb algebras, and as the monoids of Temperley-Lieb algebras are linked to situations where an endofunctor is adjoint to itself, so the monoids of simplicial endomorphisms axiomatized here are linked to arbitrary adjoint ...
متن کاملEndomorphisms of Superelliptic Jacobians
Let K be a field of characteristic zero, n ≥ 5 an integer, f(x) an irreducible polynomial over K of degree n, whose Galois group contains a doubly transitive simple non-abelian group. Let p be an odd prime, Z[ζp] the ring of integers in the pth cyclotomic field, Cf,p : y p = f(x) the corresponding superelliptic curve and J(Cf,p) its jacobian. Assuming that either n = p + 1 or p does not divide ...
متن کاملEndomorphisms of B(H
The unital endomorphisms of B(H) of (Powers) index n are classified by certain U(n)-orbits in the set of non-degenerate representations of the Cuntz algebra On on H. Using this, the corresponding conjugacy classes are identified, and a set of labels is given. This set of labels is P/ ∼ where P is a set of pure states on the UHFalgebra Mn∞ , and ∼ is a non-smooth equivalence on P . Several subse...
متن کاملA Formula for the R-matrix Using a System of Weight Preserving Endomorphisms
We give a formula for the universal R-matrix of the quantized universal enveloping algebra Uq(g). This is similar to a previous formula due to Kirillov-Reshetikhin and Levendorskii-Soibelman, except that where they use the action of the braid group element Tw0 on each representation V , we show that one can instead use a system of weight preserving endomorphisms. One advantage of our constructi...
متن کاملHyperbolic Dynamics of Endomorphisms
We present the theory of hyperbolic dynamics of endomorphisms in. Topics covered are hyperbolic sets, stable manifolds, local product structure , shadowing, spectral decomposition and ^-stability. 0. Introduction In this paper we study a smooth mapping f of a manifold M as a dynamical system. We will discuss both semilocal and global dynamical properties of f, but always under some hyperbolicit...
