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…
