About a non-standard interpolation problem
Using algebraic methods, and motivated by the one variable case, we study a
multipoint interpolation problem in the setting of several complex variables.
The duality realized by the residue generator associated with an underlying
Gorenstein algebra, using the Lagrange interpolation polynomial, plays a key
role in the arguments
Challenge IEEE-ISBI/TCB : Application of Covariance matrices and wavelet marginals
This short memo aims at explaining our approach for the challenge IEEE-ISBI
on Bone Texture Characterization. In this work, we focus on the use of
covariance matrices and wavelet marginals in an SVM classifier.Comment: 9 pages, 4 Figues, 2 Tables, Challenge IEEE-ISBI : Bone Texture

One parameter regularizations of products of residue currents
We show that Coleff-Herrera type products of residue currents can be defined
by analytic continuation of natural functions depending on one complex
variable.Comment: 8 page
Segre numbers, a generalized King formula, and local intersections
Let be an ideal sheaf on a reduced analytic space with zero
set . We show that the Lelong numbers of the restrictions to of certain
generalized Monge-Amp\`ere products , where is a tuple
of generators of , coincide with the so-called Segre numbers of
, introduced independently by Tworzewski and Gaffney-Gassler. More
generally we show that these currents satisfy a generalization of the classical
King formula that takes into account fixed and moving components of Vogel
cycles associated with . A basic tool is a new calculus for
products of positive currents of Bochner-Martinelli type. We also discuss
connections to intersection theory
