A note on geometric duality in matroid theory and knot theory

نویسندگان

چکیده

We observe that for planar graphs, the geometric duality relation generates both 2-isomorphism and abstract duality. This observation has surprising consequence links, equivalence defined by isomorphisms of checkerboard graphs is same as 2-isomorphisms graphs.

What is ”Geometric Knot Theory”?

Abstract. Using visualisation softare based on JReality I will introduce some basic notions of the classical (topologic) and geometric knot theory. I will also discuss some results from the latter field and if time allows I will present my recent result. The whole talk is ment to be very interactive and will teach you geometric knot theory mainly through graphics. No previous knowledge is requi...

Representation theory, geometric Langlands duality and categorification

The representation theory of reductive groups, such as the group GLn of invertible complex matrices, is an important topic, with applications to number theory, algebraic geometry, mathematical physics, and quantum topology. One way to study this representation theory is through the geometric Satake correspondence (also known as geometric Langlands duality). This correspondence relates the geome...

On a Unimodality Conjecture in Matroid Theory

A certain unimodal conjecture in matroid theory states the number of rank-r matroids on a set of size n is unimodal in r and attains its maximum at r = bn/2c. We show that this conjecture holds up to r = 3 by constructing a map from a class of rank-2 matroids into the class of loopless rank-3 matroids. Similar inequalities are proven for the number of non-isomorphic loopless matroids, loopless ...

on translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
