Algebraic fundamental group and simplicial complexes
In this paper we prove that the fundamental group of a simplicial complex is isomorphic to the algebraic fundamental group of its incidence algebra, and we derive some applications. AMS classification : 16E40 ; 16G20 ; 06A11 ; 55Q05 Let k be a field and A be a basic and split finite dimensional k-algebra, which means that A/r = k× k× . . .× k where r is the radical of A. There exists a unique q...
متن کاملThe Fundamental Group of Balanced Simplicial Complexes and Posets
We establish an upper bound on the cardinality of a minimal generating set for the fundamental group of a large family of connected, balanced simplicial complexes and, more generally, simplicial posets.
متن کاملAlgebraic Shifting and Sequentially Cohen-Macaulay Simplicial Complexes
Björner and Wachs generalized the definition of shellability by dropping the assumption of purity; they also introduced the h-triangle, a doubly-indexed generalization of the h-vector which is combinatorially significant for nonpure shellable complexes. Stanley subsequently defined a nonpure simplicial complex to be sequentially Cohen-Macaulay if it satisfies algebraic conditions that generaliz...
متن کاملAlgebraic Shifting and Basic Constructions on Simplicial Complexes
We try to understand the behavior of algebraic shifting with respect to some basic constructions on simplicial complexes, such as union, coning, and (more generally) join. In particular, for the disjoint union of simplicial complexes we prove ∆(K∪̇L) = ∆(∆(K)∪̇∆(L)) (conjectured by Kalai [2]), and for the join we give an example of simplicial complexes K and L for which ∆(K ∗ L) 6= ∆(∆(K) ∗∆(L)) ...
متن کاملIncidence algebras and algebraic fundamental group
One of the main tools for the study of the category of finite dimensional modules over a basic algebra, over an algebraically closed field k is its presentation as quiver and relations. This theory is mainly due to P. Gabriel (see for example [GRo]). More precisely, it has been proved that for all finite dimensional and basic algebras over an algebraically closed field k, there exists a unique ...
