Producing MathML with Tralics

Grimm, José — 2010

Towards a Digital Mathematics Library. Paris, France, July 7-8th, 2010

We describe here how Tralics can be used to convert LaTeX documents into XML or HTML. It uses an ad-hoc DTD (a simplification of the TEI), but the translation of the math formulas is conforming to the presentation MathML 2.0 recommendations. We explain how to run and parametrize the software. We give an overview of the various MathML constructs, and how they are rendered by different browsers.

La structure des sous-espaces de treillis

We study some geometrical properties of a new structure introduced by G. Pisier: the structure of lattice subspaces. We show first that if X and Y are Banach lattices such that B r ( X , Y ) = B ( X , Y ) , then X is an AL-space or Y is an AM-space. We introduce the notion of homogeneous lattice subspace and we show that up to regular isomorphism, the only homogeneous lattice subspace of L p ( Ω , μ ) , for 2≤ p < ∞, is G(I). We also show a version of the Dvoretzky theorem for this structure. We end this paper by giving an estimate...

On Denjoy-Dunford and Denjoy-Pettis integrals

José GámezJosé Mendoza — 1998

Studia Mathematica

The two main results of this paper are the following: (a) If X is a Banach space and f : [a,b] → X is a function such that x*f is Denjoy integrable for all x* ∈ X*, then f is Denjoy-Dunford integrable, and (b) There exists a Dunford integrable function f : [ a , b ] c 0 which is not Pettis integrable on any subinterval in [a,b], while ʃ J f belongs to c 0 for every subinterval J in [a,b]. These results provide answers to two open problems left by R. A. Gordon in [4]. Some other questions in connection with Denjoy-Dundord...

Dogmas and the changing images of foundations

José Ferreirós — 2005

Philosophia Scientiae

We offer a critical review of several different conceptions of the activity of foundational research, from the time of Gauss to the present. These are (1) the traditional image, guiding Gauss, Dedekind, Frege and others, that sees in the search for more adequate basic systems a logical excavation of structures, (2) the program to find sound formal systems for so-called classical mathematics that can be proved consistent, usually associated with the name of Hilbert, and (3) the historicist alternative,...
