N ov 2 00 4 On continuous extension of grafting maps

نویسنده

  • Kentaro Ito
چکیده

The definition of the grafting operation for quasifuchsian groups is extended by Bromberg [Br] to all b-groups. Although the grafting maps are not necessarily continuous at boundary groups, in this paper, we show that the grafting maps take every " standard " convergent sequence to a conver-gent sequence. As a consequence of this result, we extend Goldman's grafting theorem for quasifuchsian groups to all boundary b-groups.

In this paper we define the module extension dual Banach algebras and we use this Banach algebras to finding the relationship between weak−continuous homomorphisms of dual Banach algebras and Connes-amenability. So we study the weak∗−continuous derivations on module extension dual Banach algebras.

N ov 2 00 2 ON SIMULTANEOUS LINEAR EXTENSIONS OF PARTIAL ( PSEUDO ) METRICS

We consider the question of simultaneous extension of (pseudo)metrics defined on nonempty closed subsets of a compact metrizable space. The main result is a counterpart of the result due to Künzi and Shapiro for the case of extension operators of partial continuous functions and includes, as a special case, Banakh’s theorem on linear regular operators extending (pseudo)metrics.

We analyse certain parametrized families of one-dimensional maps with infinitely many critical points from the measure-theoretical point of view. We prove that such families have absolutely continuous invariant probability measures for a positive Lebesgue measure subset of parameters. Moreover we show that both the densities of these measures and their entropy vary continuously with the paramet...
