On dominions of certain ample monoids

چکیده
A semigroup S is called left ample if it can be embedded in the symmetric inverse IX of partial bijections a non-empty set X such that image closed under unary operation α → αα⁻¹, where α⁻¹ IX. Right semigroups are defined dually. both and right ample. monoid (left, right) as semigroup. We observe dominion an subsemigroup coincides with generated by it. then determine dominions certain submonoids In, over finite chain 1<2<⋯<n.

Right Cancellative and Left Ample Monoids: Quasivarieties and Proper Covers
The aim of this paper is to study certain quasivarieties of left ample monoids. Left ample monoids are monoids of partial one–one mappings of sets closed under the operation α 7→ αα−1. The idempotents of a left ample monoid form a semilattice and have a strong influence on the structure of the monoid; however, a left ample monoid need not be inverse. Every left ample monoid has a maximum right ...
متن کاملAmple Sheaves and Ample Families
1 Ample Sheaves Let X be a scheme and L an invertible sheaf. Given a global section f ∈ Γ(X,L ) the set Xf = {x ∈ X | germxf / ∈ mxLx} is open (MOS,Lemma 29). The inclusion Xf −→ X is affine (RAS,Lemma 6) and in particular if X is an affine scheme then Xf is itself affine. Given a sequence of global sections f1, . . . , fn the open sets Xfi cover X if and only if the fi generate L (MOS,Lemma 32...
متن کاملDominions in product varieties
Dominions, in the sense of Isbell, are investigatedin the contextof decomposable varieties of groups. An upper and lower bound for dominions in such a variety is given in terms of the two varietal factors, and the internal structure of the group being analyzed. Finally, the following result is established: If a variety N has instances of nontrivial dominions, then for any proper subvariety Q of...
متن کاملAMPLE SUBVARIETIES AND q-AMPLE DIVISORS
We introduce a notion of ampleness for subschemes of any codimension using the theory of q-ample line bundles. We also investigate certain geometric properties satisfied by ample subvarieties, e.g. the Lefschetz hyperplane theorems and numerical positivity. Using these properties, we also construct a counterexample to the converse of the Andreotti-Grauert vanishing theorem.
متن کاملAMPLE AND LEFT AMPLE SEMIGROUPS Extended
When E is actually the set of all idempotents of S, we drop the phrase “with respect to” and refer simply to the left or right ample condition. Recall that a partial permutation of a nonempty set X is a bijection σ : Y → Z for some subsets Y, Z of X, and that the set of all such partial permutations (denoted by IX) is a monoid under the usual composition of partial functions. Note that if σ : Y...
