Local Uniqueness of the Circular Integral Invariant
Integral invariants curves curve descriptors

Abstract: This article is concerned with the representation of curves by means of integral invariants. In contrast to the classical differential invariants they have the advantage of being less sensit...

In the present article we introduce two new general methods to compute the Chow motives of homogeneous varieties.
A polynomial invariant and duality for triangulations

The Tutte polynomial G(X, Y ) of a graph G is a classical invariant,important in combinatorics and statistical mechanics. An important feature of the Tutte polynomial is the duality for planar graphs...

We study 2-player impartial games, so called invariant subtraction games, of the type, given a set of allowed moves the players take turn in moving one single piece on a large Chess board towards the ...
We consider the Yamabe invariant of a compact orbifold with finitely many singular points. We prove a fundamental inequality for the estimate of the invariant from above, which also includes a criteri...
