All Maps of Type 2∞ Are Boundary Maps
نویسنده
چکیده
Let f be a continuous map of an interval into itself having periodic points of period 2n for all n ≥ 0 and no other periods. It is shown that every neighborhood of f contains a map g such that the set of periods of the periodic points of g is finite. This answers a question posed by L. S. Block and W. A.

متن کاملA Theoretical and Experimental Study of Failure Maps of Sandwich Beams with Composite Skins and Honeycomb Core
Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...

ON TYPE II0 E0-SEMIGROUPS INDUCED BY q-PURE MAPS ON Mn(C) Christopher Jankowski Robert Powers, Advisor Using a dilation theorem of Bhat, Powers has shown that every non-trivial spatial E0-semigroup can be obtained from a CP -flow acting on B(K ⊗ L(0,∞)), where K is a separable Hilbert space. In this thesis, we use boundary weight doubles (φ, ν) to define natural boundary weight maps which then ...
متن کاملNew applications of the existence of solutions for equilibrium equations with Neumann type boundary condition
Using the existence of solutions for equilibrium equations with a Neumann type boundary condition as developed by Shi and Liao (J. Inequal. Appl. 2015:363, 2015), we obtain the Riesz integral representation for continuous linear maps associated with additive set-valued maps with values in the set of all closed bounded convex non-empty subsets of any Banach space, which are generalizations of in...
متن کاملA report on “the first Concept Map Design Contest on Infection Prevention and Control”
Background Concept maps are considered not only as a powerful method of meaningful learning, but also as an instrument for evaluating the efficiency of learning. Different inquiries suggest that concept maps by promoting critical thinking and clinical reasoning may play a significant role in increasing adherence to infection prevention methods and therefore reduce healthcare-associated infectio...
