متن کاملMonomial Resolutions
Let M be a monomial ideal in the polynomial ring S = k[x1, . . . , xn] over a field k. We are interested in the problem, first posed by Kaplansky in the early 1960’s, of finding a minimal free resolution of S/M over S. The difficulty of this problem is reflected in the fact that the homology of arbitrary simplicial complexes can be encoded (via the Stanley-Reisner correspondence [BH,Ho,St]) int...
متن کاملPath categories and resolutions
The path category P (X) of a simplicial set X defines a functor X 7→ P (X) which is left adjoint to the nerve functor B : cat → sSet. The first section of this paper contains an elementary description of this functor, with some of its basic properties. This construction specializes to a path category functor for cubical sets which appears in the second section. The path category construction is...

متن کاملCrepant Resolutions of C
In this article, we determine the explicit toric variety structure of Hilb1(Cn) for n = 4, 5, where A1(n) is the special diagonal group of all order 2 elements. Through the toric data of Hilb1(Cn), we obtain certain toric crepant resolutions of C/A1(n), and the different crepant resolutions are connected by flops of n-folds for n = 4, 5. 2000 MSC: 14M25,14J17, 20C33
