On Kiselman Quotients of 0-hecke Monoids
Combining the definition of 0-Hecke monoids with that of Kiselman semigroups, we define what we call Kiselman quotients of 0-Hecke monoids associated with simply laced Dynkin diagrams. We classify these monoids up to isomorphism, determine their idempotents and show that they are J -trivial. For type A we show that Catalan numbers appear as the maximal cardinality of our monoids, in which case ...
متن کاملSome Basic Results on Actions of Non-affine Algebraic Groups
We study actions of connected algebraic groups on normal algebraic varieties, and show how to reduce them to actions of affine subgroups. This yields a structure theorem for normal equivariant embeddings of semi-abelian varieties, and a characteristic-free version of the Borel–Remmert theorem.

متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
