How does an algebraic geometer learning secant forms additional the knowledge of speculation checks in facts? Why could a statistician engaged on issue research increase open difficulties approximately determinantal types? Connections of this sort are on the middle of the hot box of "algebraic statistics".

T ??  f / Y . 1. — Supposons que tp : Xp → Yp soit un isomorphisme pour p ≤ n. Alors, pour tout Faisceau F de SF , et at induit un isomorphisme ∼ τ

D´emonstration. 1). Ici, on s’int´eresse avant tout `a t = f• : X• → S∆ . On va approximer t de proche en proche : on a une factorisation X · · · → cosqn+1 (X) → cosqn (X) · · · → cosq−1 (X) = S∆ . c) qu’on a une identification cosqm ◦ cosqn = cosqn pour m ≥ n. La fl`eche cosqn+1 (X) → cosqn (X) s’interpr`ete alors comme une fl`eche ˜ τ : cosqn+1 (X) → cosqn+1 (X) ˜ = cosqn (X). Remarquons que τp est un isomorphisme si p ≤ n, cette fl`eche s’identifiant o` u l’on a pos´e X a l’identit´e de ` ˜ p=X ˜ p = cosqn (X)p = Xp .
