N ov 2 00 8 INVARIANT HILBERT SCHEMES AND WONDERFUL VARIETIES STÉPHANIE

چکیده
The invariant Hilbert schemes considered in [4] were proved to be affine spaces. The proof relied on the classification of strict wonderful varieties. We obtain in the present article a classification-free proof of the affinity of these invariant Hilbert scheme by means of deformation theoretical arguments. As a consequence we recover in a shorter way the classification of strict wonderful varieties. This provides an alternative and new approach to answer Luna’s conjecture.

We consider stratifications of schemes by subvarieties, and introduce the notion of a stratification generated by a collection of (reduced) subschemes. We recall some basics of Gröbner degenerations (just for lex order) and Stanley-Reisner theory. We then state the main theorem, that the lex init of a Kazhdan-Lusztig variety in BottSamelson coördinates is the Stanley-Reisner scheme of a subword...
متن کاملA Unified Approach To Construct Non-perfect Secret Sharing And Traitor Tracing Schemes
In this paper, we explore some of the wonderful characteristics of the C3,3 = [110; 101; 011] codebook when viewed from different angles. The information contained in this codebook implicitly carries the properties of inheritance, association and also a way to segment and mix two different binary sequences, thus, sowing the seed for taking a unified approach: (i) to construct simple non-perfect...
متن کاملA Note on Mustaţă’s Computation of Multiplier Ideals of Hyperplane Arrangements
In [7], M. Mustaţă used jet schemes to compute the multiplier ideals of reduced hyperplane arrangements. We give a simpler proof using a log resolution and generalize to non-reduced arrangements. By applying the idea of wonderful models introduced by De Concini–Procesi [1], we also simplify the result. Indeed, Mustaţă’s result expresses the multiplier ideal as an intersection, and our result us...
متن کاملEfficient Electronic Gambling: An Extended Implementation of the Toolbox for Mental Card Games
There are many wonderful protocols in cryptography which are still waiting for their realization. Here we consider efficient solutions for secure electronic card games. Our contribution seems to be the first known practical implementation that requires no trusted third-party and simultaneously keeps the players’ strategies confidential. The provided open source library LibTMCG can be used for c...
متن کاملخورجین و گونههای مختلف آن در استان چهارمحال و بختیاری
During collecting information regarding “kilims” in Chaharmahal-va-Bakhtiari province, it was understood that whatever we recognize under the general term of “Khorjin” can be divided into three categories: small, normal and big ones as described below. (1) Small Khorjins (50×25 cm) which are weaved in both parts of province, i.e. Chaharmahal & also Bakhtiari. They ...
