A Group-theory Method to The Cycle Structures of Feedback Shift Registers
feedback shift register cycle structure symmetric group
2015/12/31
In this paper, we consider the cycle structures of feedback shift registers (FSRs).
At the beginning, the cycle structures of two special classes of FSRs, pure circulating
registers (PCRs) and pure ...
This paper records the path of a letter that Marty Isaacs wrote to a stranger. The tools in the letter are used to illustrate a di erent way of studying random walk on the Heisenberg group. The author...
CARRIES, GROUP THEORY, AND ADDITIVE COMBINATORICS
Data occurred along the equalization algorithm minimize proportion
2015/7/7
When numbers are added in the usual way carries occur along the route. These carries cause a mess and it is natural to seek ways to minimize them. This paper proves that balanced arithmetic minimizes ...
Sieve methods in group theory I: Powers in Linear groups
Sieve Property-T Powers Linear groups Finite groups of Lie type
2011/9/14
Abstract: A general sieve method for groups is formulated. It enables one to "measure" subsets of a finitely generated group. As an application we show that if $\Gamma$ is a finitely generated non vir...
Orbit Equivalence and Measured Group Theory
Orbit equivalence Measured group theory von Neumann algebras
2010/11/26
We give a survey of various recent developments in orbit equivalence and measured group theory. This subject aims at studying infinite countable groups through their measure preserving actions.
We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in...

On public-key cryptosystems based on combinatorial group theory
Public-key cryptosystem combinatorial group theory Richard Thompson groups
2009/1/20
We analyze and critique the public-key cryptosystem, based on
combinatorial group theory, that was proposed by Wagner and Magyarik
in 1984. This idea is actually not based on the word problem but on...
Towards Provably Secure Group Key Agreement Building on Group Theory
group key establishment provable security conjugacy problem automorphisms of groups
2008/11/3
Known proposals for key establishment schemes based on
combinatorial group theory are often formulated in a rather informal
manner. Typically, issues like the choice of a session identifier and para...
Weyl and von Neumann: Symmetry, Group Theory, and Quantum Mechanics
symmetry groups quantum mechanics structural realism
2008/4/18
In this paper, I shall discuss the heuristic role of symmetry in the mathematical formulation of quantum mechanics. I shall first set out the scene in terms of Bas van Fraassen’s elegant presentation ...
