K-theory for group C*-algebras
No full textThese notes are based on a lecture course given by the first author in the Sedano Winter School on K-theory held in Sedano, Spain, on January 22-27th of 2007. They aim at introducing K-theory of C*-algebras, equivariant K-homology and KK-theory in the context of the Baum-Connes conjectur
Local-global principle for the Baum-Connes conjecture with coefficients
No full textWe establish the Hasse principle (local-global principle) in the context of the Baum–Connes conjecture with coefficients. We illustrate this principle with the discrete group GL(2,F) where F is any global field
A proof of the Baum-Connes conjecture for reductive adelic groups
No full textLet F be a global field, A its ring of adeles, G a reductive group over F. We prove the Baum–Connes conjecture for the adelic group View the MathML source
Interview with Christopher F. Baum on An introduction to Stata programming, by Christopher F. Baum
No full textAn Introduction to Stata Programming covers three types of programming that can be used in working with Stata: do-file programming, ado-file programming, and Mata functions that work in conjunction with do- and ado-files. Baum places emphasis on how you can usefully automate Stata more effectively. The introductory chapters discuss why you should invest time and effort in learning Stata programming, and the present elementary concepts of the command-line interface and some commonly used tools for working with programs and datasets.Title supplied by cataloger

Determination of baum-bott residues of higher codimensional foliations
No full textLet F be a singular holomorphic foliation, of codimension k, on a complex compact manifold such that its singular set has codimension ≥ k+1. In this work we determinate Baum-Bott residues for F with respect to homogeneous symmetric polynomials of degree k + 1. We drop the Baum-Bott's generic hypothesis and we show that the residues can be expressed in terms of the Grothendieck residue of an one-dimensional foliation on a (k + 1)-dimensional disc transversal to a (k +1)-codimensional component of the singular set of F. Also, we show that Cenkl's algorithm for non-expected dimensional singularities holds dropping the Cenkl's regularity assumption
EXTENDED BAUM TRANSFORMATIONS FOR GENERAL FUNCTIONS, II
No full textThe discrimination technique for estimating the parameters of Gaussian mixtures that is based on the Extended Baum transformations (EB) has had significant impact on the speech recognition community. The proof that definitively shows that these transformations increase the value of an objective function with iteration (i.e., so-called "growth transformations") was presented by the author two years ago for a diagonal Gaussian mixture densities. In this paper this proof is extended to a multidimensional multivariate Gaussian mixtures. The proof presented in the current paper is based on the linearization process and the explicit growth estimate for linear forms of Gaussian mixtures
