Observations on complete sets between linear time and polynomial time [PDF]

, 2011
There is a single set that is complete for a variety of nondeterministic time complexity classes with respect to related versions of m-reducibility. This observation immediately leads to transfer results for determinism versus nondeterminism solutions ...

Fitting Ranked English and Spanish Letter Frequency Distribution in U.S. and Mexican Presidential Speeches

, 2011
The limited range in its abscissa of ranked letter frequency distributions causes multiple functions to fit the observed distribution reasonably well.

Limits of Baumslag-Solitar groups and dimension estimates in the space of marked groups [PDF]

, 2010
We prove that the limits of Baumslag-Solitar groups which we previously studied are non-linear hopfian C*-simple groups with infinitely many twisted conjugacy classes.

Applications of Finite Model Theory: Optimisation Problems, Hybrid Modal Logics and Games. [PDF]

, 2013
There exists an interesting relationships between two seemingly distinct fields: logic from the field of Model Theory, which deals with the truth of statements about discrete structures; and Computational Complexity, which deals with the classification ...
