N -expansive Homeomorphisms on Surfaces
We exploit the techniques developed in [Le] to study N -expansive homeomorphisms on surfaces. We prove that when f is a 2-expansive homeomorphism defined on a compact boundaryless surface M with nonwandering set Ω(f) being the whole of M then f is expansive. This condition on the nonwandering set cannot be relaxed: we present an example of a 2-expansive homeomorphisms on a surface with genus 2 ...

متن کاملExpansive Homeomorphisms on Compact Manifolds
In this paper theorems are proved which provide for lifting and projecting expansive homeomorphisms through pseudocovering mappings so that the lift or projection is also an expansive homeomorphism. Using these techniques it is shown that the compact orientable surface of genus 2 admits an expansive homeomorphism.
متن کاملAn Improved Attack on WG Stream Cipher
WG is a synchronous stream cipher submitted to the hardware profile of eSTREAM project. The main feature of this stream cipher is the use of WG transformation. WG uses keys and initial vectors (IVs) of the same lengths 80, 96, 112 and 128 bits. Moreover, IVs of the length 32 and 64 bits are admitted. The most important key recovery attack on WG was presented by Wu and Preneel and uses the weakn...
