A Numerical Characterization of Gorenstein Complexes
Let V be a finite set, called the vertex set, and let .1 be a simplicial complex on V. Thus .1 is a collection of subsets of V such that (i) {x} EL1 for any x E V, and (ii) a E .1, 'r c a imply 'r E L1. An element a of .1 is called an i-face if #( a) = i + 1. Here, #( a) is the cardinality of a as a set. The positive integer dim .1: = max{ #( a) 1; a E L1} is called the dimension of .1. Let v =...

synthesis and characterization of potentially biological active cyclometallated organoplatinum(ii) complexes
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
15 صفحه اولPREPARATION AND CHARACTERIZATION OF Mn (III) COMPLEXES
We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted
متن کاملStellar subdivisions and Stanley-Reisner rings of Gorenstein complexes
Unprojection theory analyzes and constructs complicated commutative rings in terms of simpler ones. Our main result is that, on the algebraic level of Stanley-Reisner rings, stellar subdivisions of Gorenstein* simplicial complexes correspond to unprojections of type Kustin-Miller. As an application of our methods we study the minimal resolution of Stanley– Reisner rings associated to stacked po...
