Navigating in the Cayley graph of $SL_2(F_p)$ and applications to hashing [PDF]

open access: yes, 2014
Cayley hash functions are based on a simple idea of using a pair of (semi)group elements, $A$ and $B$, to hash the 0 and 1 bit, respectively, and then to hash an arbitrary bit string in the natural way, by using multiplication of elements in the (semi ...

Dominoes over a free monoid

open access: yesTheoretical Computer Science, 1982
AbstractDominoes over a free monoid and operations on them are introduced. Related algebraic systems and their applications to decidability problems about morphisms on free monoids are studied. A new simple algorithm for testing DOL sequence equivalence is presented.

Homology of Gaussian groups

open access: yes, 2001
We describe new combinatorial methods for constructing an explicit free resolution of Z by ZG-modules when G is a group of fractions of a monoid where enough least common multiples exist (``locally Gaussian monoid''), and, therefore, for computing the ...

Discrete Event Systems Theory for Fast Stochastic Simulation via Tree Expansion

open access: yesSystems
Paratemporal methods based on tree expansion have proven to be effective in efficiently generating the trajectories of stochastic systems. However, combinatorial explosion of branching arising from multiple choice points presents a major hurdle that must
