On Galvin's lemma and Ramsey spaces [PDF]

open access: yesAnnals of Combinatorics 16 (2002), no. 2, 319-330, 2009
An abstract version of Galvin's lemma is proven, within the framework of the theory of Ramsey spaces. Some instances of it are explored.

The Combinatorics of Iterated Loop Spaces

open access: yes, 2003
It is well known since Stasheff's work that 1-fold loop spaces can be described in terms of the existence of higher homotopies for associativity (coherence conditions) or equivalently as algebras of contractible non-symmetric operads.

General combinatorical structure of truth tables of bracketed formulae connected by implication [PDF]

open access: yesarXiv, 2012
In this paper we investigate the general combinatorical structure of the truth tables of all bracketed formulae with n distinct variables connected by the binary connective of implication, an m-implication.

Teaching of probability theory and combinatorics at secondary schools

open access: yesLietuvos Matematikos Rinkinys, 2004
The topics of probability theory and combinatorics were brought into curricula of Lithuanian secondary schools ten years ago. The problems of teaching and actual situation of apprehension of concepts of prob­ability theory and combinatorics are analyzed.

Hyperbolicity and stable polynomials in combinatorics and probability [PDF]

open access: yesarXiv, 2012
This was the basis of two lectures in the Current Developments in Mathematics conference in 2011. These lectures survey the theory of hyperbolic and stable polynomials, from their origins in the theory of linear PDE's to their present uses in combinatorics and probability theory.

Combinatorics of balanced carries [PDF]

open access: yes, 2013
We study the combinatorics of addition using balanced digits, deriving an analog of Holte's "amazing matrix" for carries in usual addition. The eigenvalues of this matrix for base b balanced addition of n numbers are found to be 1,1/b,...,1/b^n, and ...

The Turań Number of 2P7

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The Turán number of a graph H, denoted by ex(n, H), is the maximum number of edges in any graph on n vertices which does not contain H as a subgraph. Let Pk denote the path on k vertices and let mPk denote m disjoint copies of Pk.
