Unicode et typographie : un amour impossible

In this paper we give a new approach to the concepts of glyph and character, applied to the study of the Unicode encoding. After a thorough discussion of these two concepts, we describe the other fundamental ingredients of the encoding: privileged glyphs, character descriptions, combining characters, and properties. In each case we try to show the importance of the given notion and at the same ...

Sur l ’ équation div u = f

The main result is the following. Let be a bounded Lipschitz domain in Rd , d 2. Then for every f ∈ Ld( ) with ∫ f = 0, there exists a solution u ∈ C0( ) ∩ W1,d ( ) of the equation divu= f in , satisfying in addition u= 0 on ∂ and the estimate ‖u‖L∞ + ‖u‖W1,d C‖f ‖Ld , where C depends only on . However one cannot choose u depending linearly on f . To cite this article: J. Bourgain, H. Brezis, C...

Étude d'une équation intégrale avec des méthodes combinatoires

0 f(t) dt = δ(f(x)− f(0)) pour tout x ≥ 0. (Eλ,δ) Remarquons tout d’abord que le paramètre δ est accessoire : si f est solution de (Eλ,δ) alors g(x) = f(|δ|x) est solution de (Eλ,1) ou (Eλ,−1). Cependant, il s’avère naturelle de considérer des paramètres λ et δ entiers dans notre construction. Nous faisons quelques remarques sur les solutions de cette équation. Nous présentons ensuite une métho...

Impossible Frontiers

A key result of the Capital Asset Pricing Model (CAPM) is that the market portfolio— the portfolio of all assets in which each asset’s weight is proportional to its total market capitalization—lies on the mean-variance-efficient frontier, the set of portfolios having mean-variance characteristics that cannot be improved upon. Therefore, the CAPM cannot be consistent with efficient frontiers for...

Impossible Words?

The idea that quotidian, middle-level concepts typically have internal structure-definitional, statistical, or whatever—plays a central role in practically every current approach to cognition. Correspondingly, the idea that words that express quotidian, middle-level concepts have complex representations "at the semantic level" is recurrent in linguistics; it is the defining thesis of what is of...
