This quantity covers many subject matters together with quantity concept, Boolean features, combinatorial geometry, and algorithms over finite fields. This publication includes many fascinating theoretical and applicated new effects and surveys awarded by way of the simplest experts in those components, equivalent to new effects on Serre's questions, answering a query in his letter to most sensible; new effects on cryptographic purposes of the discrete logarithm challenge on the topic of elliptic curves and hyperellyptic curves, together with computation of the discrete logarithm; new effects on functionality box towers; the development of latest sessions of Boolean cryptographic features; and algorithmic functions of algebraic geometry.

This quantity comprises the papers provided on the IUTAM Symposium on Geometry and information of Turbulence, held in November 1999, on the Shonan overseas Village heart, Hayama (Kanagawa-ken), Japan. The Symposium used to be proposed in 1996, aiming at organizing concen trated discussions on present realizing of fluid turbulence with empha sis at the data and the underlying geometric buildings.

Blowing-up along a submanifold. Let M be a complex manifold, and N ⊂ M a closed submanifold. The blowing-up of M along N is a manifold W equipped with a surjective mapping π : W → M such that π induces an isomorphism between W \ π −1 (N ) and M \ N , and whose construction can be described locally. We replace M by an open ball B ⊂ Cn , and N by the submanifold of B deﬁned by the equations z 1 = 0, . . , z p = 0. We can assume that B = Bp × Bn−p where Bp ⊂ Cp has coordinates z 1 , . . , z p and Bn−p ⊂ Cn−p has coordinates z p+1 , .
5) is not exact in general. 5) gives rise in fact to the cohomology theory of sheaves. Nevertheless: if G 0 E F is an exact sequence of sheaves, for each open set U ⊂ X the sequence 0 E(U ) F (U ) G(U ) is exact. Let us note also that there is no useful deﬁnition of exact sequence for presheaves. Nevertheless the following remark will be helpful. 1. Let Fn−1 ··· fn−1 Fn fn Fn+1 ··· be a sequence of morphisms of presheaves such that for any open set U ⊂ X the induced sequence ··· Fn−1 (U ) fn−1,U Fn (U ) fn,U ··· Fn+1 (U ) is exact.
I Ui an open (3) for any open set U ⊂ X, any open covering U = i Ui of U and sections si ∈ F (Ui ) with si |Ui ∩Uj = sj |Ui ∩Uj there exists s ∈ F(U ) such that s|U = si . Such s is unique by (2). A sub(pre)-sheaf of F is a (pre)-sheaf G such that G(U ) ⊂ F(U ) is a subgroup (a vector subspace. . ) and the restrictions in G are induced by those in F . If a presheaf F is not a sheaf, one can construct the associated sheaf F˜ simply by adding to each F (U ) the missing sections: an element of F˜ (U ) is a family (si ∈ F (Ui )) with si |Ui ∩Uj = sj |Ui ∩Uj , U = i Ui being an open covering (two such families must be identiﬁed if their restrictions to some reﬁnement of the respective coverings coincide).
