We study the geometry of horospheres in Teichmüller space Riemann surfaces genus g with n punctures, where 3g-3+n≥2. show that every C 1 -diffeomorphism to itself preserves is an element extended mapping class group. Using relation between and metric balls, we obtain a new proof Royden’s Theorem isometry group

In this paper, we introduce a new kind of order, Cesaro supermodular order, which includes supermodular order and stochastic order. For this new order, we show that it almost fulfils all desirable properties of a multivariate positive dependence order that have been proposed by Joe (1997). Also, we obtain some relations between it with other orders. Finally, we consider different issues related...

A new variation of the coloring problem, μ-coloring, is defined in this paper. Given a graph G and a function μ, a μ-coloring is a coloring where each vertex v of G must receive a color at most μ(v). It is proved that μ-coloring lies between coloring and list-coloring, in the sense of generalization of problems and computational complexity. The notion of perfection is extended for μ-coloring, l...
