Centroids and the rapid decay property in mapping class groups
نویسندگان
چکیده
We study a notion of an equivariant, Lipschitz, permutationinvariant centroid for triples of points in mapping class groups MCG(S), which satisfies a certain polynomial growth bound. A consequence (via work of Druţu-Sapir or Chatterji-Ruane) is the Rapid Decay Property for MCG(S).

Characterization of weak fixed point property for new class of set-valued nonexpansive mappings
In this paper, we introduce a new class of set-valued mappings which is called MD-type mappings. This class of mappings is a set-valued case of a class of the D-type mappings. The class of D-type mappings is a generalization of nonexpansive mappings that recently introduced by Kaewkhao and Sokhuma. The class of MD-type mappings includes upper semi-continuous Suzuki type mappings, upper semi-con...
متن کاملEmbedding Median Algebras in Products of Trees
We show that a metric median algebra satisfying certain conditions admits a bilipschitz embedding into a finite product of R-trees. This gives rise to a characterisation of closed connected subalgebras of finite products of complete R-trees up to bilipschitz equivalence. Spaces of this sort arise as asymptotic cones of coarse median spaces. This applies to a large class of finitely generated gr...
متن کاملSome Geometric Groups with Rapid Decay
We explain simple methods to establish the property of Rapid Decay for a number of groups arising geometrically. Those lead to new examples of groups with the property of Rapid Decay, notably including non-cocompact lattices in rank one Lie groups.
متن کاملRelatively Hyperbolic Groups with Rapid Decay Property
We prove that a finitely generated group G hyperbolic relative to the collection of finitely generated subgroups {H1, . . . , Hm} has the Rapid Decay property if and only if each Hi , i = 1, 2, . . . ,m, has the Rapid Decay property.
متن کاملExistence Results of best Proximity Pairs for a Certain Class of Noncyclic Mappings in Nonreflexive Banach Spaces Polynomials
Introduction Let be a nonempty subset of a normed linear space . A self-mapping is said to be nonexpansive provided that for all . In 1965, Browder showed that every nonexpansive self-mapping defined on a nonempty, bounded, closed and convex subset of a uniformly convex Banach space , has a fixed point. In the same year, Kirk generalized this existence result by using a geometric notion of ...
