On p-intersection representations
For a graph G = (V, E) and integer p, a p-intersection representation is a family = {Sx: x E V} of subsets of a set S with the property that IS, n S,l 2 p {u, u } E E. It is conjectured in 111 that 8,(G) I B(K,,/2,,,/2)(1 + o(1)) holds for any graph with n vertices. This is known to be true for p = 1 by [41. In [ I ] , O(K,,/2,,,/2) 1 (n2 + (2p l)n)/4p is proved for any n and p. Here, we show t...
متن کامل$G$-Weights and $p$-Local Rank
Let $k$ be field of characteristic $p$, andlet $G$ be any finite group with splitting field $k$. Assume that $B$ is a $p$-block of $G$.In this paper, we introduce the notion of radical $B$-chain $C_{B}$, and we show that the $p$-local rank of $B$ is equals the length of $C_{B}$. Moreover, we prove that the vertex of a simple $kG$-module $S$ is radical if and only if it has the same vertex of th...
متن کاملLearning Robust Low-Rank Representations
In this paper we present a comprehensive framework for learning robust low-rank representations by combining and extending recent ideas for learning fast sparse coding regressors with structured non-convex optimization techniques. This approach connects robust principal component analysis (RPCA) with dictionary learning techniques and allows its approximation via trainable encoders. We propose ...
متن کاملOn the Rank of p-Schemes
Let n > 1 be an integer and p be a prime number. Denote by Cpn the class of non-thin association p-schemes of degree pn. A sharp upper and lower bounds on the rank of schemes in Cpn with a certain order of thin radical are obtained. Moreover, all schemes in this class whose rank are equal to the lower bound are characterized and some schemes in this class whose rank are equal to the upper bound...
متن کاملConstruction of Low Rank Vector Bundles on P and P
We describe a technique which permits a uniform construction of a number of low rank bundles, both known and new. In characteristic two, we obtain rank two bundles on P5. In characteristic p, we obtain rank two bundles on P4 and rank three bundles on P5. In arbitrary characteristic, we obtain rank three bundles on P4 and rank two bundles on the quadric S5 in P6.
