On the equidistribution of unstable curves for pseudo-Anosov diffeomorphisms of compact surfaces

Pseudo-anosov Maps and Simple Closed Curves on Surfaces

Suppose C and C are two sets of simple closed curves on a hyperbolic surface F . We will give necessary and sufficient conditions for the existence of a pseudo-Anosov map g such that g(C) ∼= C. Pseudo-Anosov maps are the most important class among surface homeomorphisms [Th3], and they play important roles in 3-manifold theory [Th2]. This note is to address the following question: Suppose F is ...

Pseudo-anosov Foliations on Periodic Surfaces

In this note we shall study the lifts of stable foliations of pseudo-Anosov diffeomorphism to certain infinite abelian covers. This is motivated, at least in part, by recent progress in understanding the ergodic properties of the analogous horocycle flows on infinite surfaces [3],[13]. Our aim is to show that many of the results from that context hold in this natural and technically simpler set...

Minimal pseudo-Anosov translation lengths on the complex of curves

Let Sg,n be an orientable surface with genus g and n punctures. For simplicity, we shall drop the subscripts and denote it by S . The complex of curves C(S), is a locally infinite simplicial complex whose vertices are the isotopy classes of essential, non-peripheral, simple closed curves on S . A collection of vertices span a simplex if the curves can be isotoped to be disjoint or minimally int...

“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
