A unique factorization theorem for matroids

Henry Crapo, William Schmitt

We study the combinatorial, algebraic and geometric properties of the free product operation on matroids. After giving cryptomorphic definitions of free product in terms of indepen…

The Free product of Matroids

Henry Crapo, William Schmitt

We introduce a noncommutative binary operation on matroids, called free product. We show that this operation respects matroid duality, and has the property that, given only the car…

Search for different links with the same Jones' type polynomials: Ideas from graph theory and statistical mechanics

Jozef H. Przytycki

We describe in this talk three methods of constructing different links with the same Jones type invariant. All three can be thought as generalizations of mutation. The first combin…

From 3-moves to Lagrangian tangles and cubic skein modules

Jozef H. Przytycki

We discuss several open problems in classical Knot Theory and we develop techniques that allow us to study them: Lagrangian tangles, skein modules and Burnside groups.

Symmetric knots and billiard knots

Jozef H. Przytycki

Symmetry of geometrical figures is reflected in regularities of their algebraic invariants. Algebraic regularities are often preserved when the geometrical figure is topologically…

The topological interpretation of the core group of a surface in S^4

Jozef H. Przytycki, Witold Rosicki

We give a topological interpretation of the core group invariant of a surface embedded in S^4. We show that the group is isomorphic to the free product of the fundamental group of…
