M ay 2 00 8 Rotation set for maps of degree 1 on the graph sigma
For a continuous map on a topological graph containing a unique loop S it is possible to define the degree and, for a map of degree 1, rotation numbers. It is known that the set of rotation numbers of points in S is a compact interval and for every rational r in this interval there exists a periodic point of rotation number r. The whole rotation set (i.e. the set of all rotation numbers) may no...
متن کامل“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...
15 صفحه اولRotation Sets for orbits of Degree One Circle Maps
Let F be the lifting of a circle map of degree one. In [?] a notion of F -rotation interval of a point x ∈ S was given. In this paper we define and study a new notion of a rotation set of a point which preserves more of the dynamical information contained in the sequences {F(y)}n=0 than the preserved by the one from [?]. In particular, we characterize dynamically the endpoints of these sets and...
متن کاملRotation Sets for Some Non–continuous Maps of Degree One
Iteration of liftings of non necessarily continuous maps of the circle into itself are considered as discrete dynamical systems of dimension one. The rotation set has proven to be a powerful tool to study the set of possible periods and the behaviour of orbits for continuous and old heavy maps. An extension of the class of maps for which the rotation set maintains this power is given.
متن کاملStructure of the Fixed Point of Condensing Set-Valued Maps
In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.
