We are interested in the essential dimension edk X, which is the essential dimension of the functor sending an extension K of k into the set of isomorphism classes of objects of X(K)

Russell used acquaintance to that effect: ÒI say that I am acquainted with an object when I have a direct cognitive relation to that object, that is when I am directly aware of

Proposition Une matrice A (resp. un endomorphisme u d’un espace de di- mension finie E) est diagonalisable si et seulement si il existe un poly- nôme annulateur de A (resp.

– Selective publishing of results: Due to the pressure of publishing positive results, researchers opt to select a part of the results that supports their hypothesis and ignore

i) We need two image charges, one for each one of the real charges producing the constant external electric field.. The first term is just the potential due to the external field

We begin with the following inequality for Stieltjes integrals. This inequality is sharp.. constant, and hence a.e. We shall base the proof of this fact on a similar result

Because the box dimension of a set is always greater or equal to its Hausdorff dimension, the inequality of our theorem, also gives an upper bound for the Hausdorff dimension.. If the

Isto não acontece porque careçam de órgãos, pois as pegas e os papagaios podem proferir palavras, mas não falar como nós, isto é, testemunhando que pensam o que dizem, ao passo que

The phasing of precession and obliquity appears to influence the persistence of interglacial conditions over one or two in- solation peaks: the longest interglacials are
