Whitney equisingularity, euler obstruction and invariants of map germs from Cn to C3, n > 3
(2007-01-01)
We study how to minimize the number of invariants that is sufficient for the Whitney equisingularity of a one parameter deformation of any finitely determined holomorphic germ f : (Cn, 0) → (C3, 0), with n > 3. Gaffney ...
A simple way of approximating the canonical partition functions in statistical mechanics
(IOP Publishing, 2015-09)
We propose a simple pedagogical way of introducing the Euler-MacLaurin summation formula in an undergraduate course on statistical mechanics. The reason is that the students may feel more comfortable and confident if they ...

Among the many methodological resources that the mathematics teacher can use in the classroom, we can cite the History of Mathematics which has contributed to the development of activities that promotes students curiosity ...
On Chern's conjecture about the Euler characteristic of affine manifolds
(2018)
The development the theory of characteristic classes allowed Shiing-Shen Chern to generalize the Gauss Bonnet theorem to Riemannian manifolds of arbitrary dimension. The Chern Gauss Bonnet theorem expresses the Euler ...
Fourier coefficientes computation in two variables, a distributional versionCáluculo de Coeficientes de Fourier en dos variables, una versión distribucional
(2015-01-01)
The present article, by considering the distributional summations of Euler-Maclaurin and a suitable choice of the distribution, results in repre- sentations for the Fourier coefficients in two variables are obtained. These ...
Polar Multiplicities and Euler obstruction of the stable types in weighted homogeneous map germs from C-n to C-3 n >= 3
(World Scientific Publ Co Pte Ltd, 2007-01-01)
In this article we show that for corank 1, quasi-homogeneous and finitely determined map germs f : (C-n, 0)-> (C-3, 0), n >= 3 one can obtain formulae for the polar multiplicities defined on the following stable types of ...

The Euler obstruction and torus action
(SpringerDordrecht, 2015-04)
In this paper we study surfaces with the property that their irreducible components are toric surfaces. In particular, we present a formula to compute the Euler obstruction of such surfaces. As an application of this formula ...
