Báo cáo toán học: "The Skeleton of a Reduced Word and a Correspondence of Edelman and Greene" pot

... Macdonald as a second special case. The main purpose of this paper is to give a planarized construction and proof for the bijection of Edelman and Greene between reduced words and certain pairs of ... Similarly a partial arrangement is an isomorphism class of simple marked partial arrangements of pseudolines. Goodman and Pollack [8] described a one-to-many corre...

... If p a contains more than one vertex (say p a = a, a 2 , a 3 , . . . , a n ), then (a, a 2 ) is lonely since p a is a path in L C (G). But {a} is a singleton color class, so (a 2 , a) is also lonely. ... Hence, by Lemma 2.1, swapping a and a 2 yields another optimal coloring C  of G. To apply the minimality condition, we need to show that p  a = a 2 , a 3...

... one hand, as T could be a star, it is clear that we need that G has a vertex of degree at least k. On the other hand, we also need a certain amount of vertices of large degree. In fact, the amount ... paper, we shall consider a special subclass of caterpillars, namely those that have at most two vertices of degree greater than 2. Observe that any such caterpillar T can be ob...

In this case, we call ... investigated the translational hull of a type -A semigroup, in particular, the result obtained by Ault [1] was sub- stantially generalized and extended. Thus, the transl...
