15 صفحه اول-Solid Varieties of Languages
In this paper, a characterization of the language varieties and congruence varieties corresponding to M -solid pseudovarieties is presented. Taking into account the isomorphisms of the Eilenberg-type correspondences, each complete sublattice of pseudovarieties corresponds to a complete sublattice of language varieties, as well as another one of congruence varieties. For the varieties of tree la...
متن کاملEigenvalue Comparison on Bakry-emery Manifolds
It is called shrinking, steady, or expanding soliton if a > 0, a = 0 or a < 0 respectively. More generally (M, g, f) is called a Bakry-Emery manifold if the so-called Bakry-Emery Ricci tensor Rcij + fij ≥ agij for some a ∈ R. In this paper we apply the modulus of continuity estimates developed in [AC,AC2,AC3] to give a different proof of an eigenvalue comparison estimate on Bakry-Emery manifold...
متن کاملMulti-solid Varieties
We consider the concepts of colored terms and multihypersubstitutions. If t ∈ Wτ (X) is a term of type τ , then any mapping αt : Pos (t) → IN of the non-variable positions of a term into the set of natural numbers is called a coloration of t. The set W c τ (X) of colored terms consists of all pairs 〈t, αt〉. The set Hyp(τ) of all hypersubstitutions of type τ is a countable monoid. If M is a subm...
