Towards a functor between affine and finite Hecke categories in type A
… Hecke category, partly categorifying a certain natural homomorphism of the corresponding Hecke algebras. This homomorphism sends generators of the Bernstein's commutative subalgebra inside the affine Hecke algebra to Jucys-Murphy elements in the finite Hecke algebra. Construction employs the …

The Equivalence "t" on ω-Orthodox Semigroups.
If X is a subset of a semigroup, E(X) will denote the set of idempotents of X. A regular semigroup S will be termed an w-orthodox semigroup if E(S) is an ω-chain of rectangular bands (Ennen, the non-negative integers).
