Edge ideals: algebraic and combinatorial properties
Edge ideal regularity associated prime sequentially Cohen-Macaulay
2010/12/31
Let C be a clutter and let I(C) R be its edge ideal. This is a survey paper on
the algebraic and combinatorial properties of R/I(C) and C, respectively. We give a criterion to estimate the regulari...
Dichotomy theorems for random matrices and closed ideals of operators on $\big(\bigoplus_{n=1}^\infty\ell_1^n \big)_{\mathrm{c}_0}$
Dichotomy random matrices closed ideals of operators
2010/9/1
We prove two dichotomy theorems about sequences of operators into L1 given by random matrices. In the second theorem we assume that the entries of each random ma-trix form a sequence of independent, s...
