Hilbert series, Poincaré series and homotopy Lie algebras of graded algebras -- a seminar
Clas Löfwall
We begin with proving a formula relating the Hilbert series of a graded algebra and the Poincaré series for in two variables. This gives the Fröberg formula in the case whe…
The holonomy Lie algebra of a matroid
Clas Löfwall
We will start from the beginning and define a matroid and its Orlik-Solomon algebra and holonomy Lie algebra, but first we give some background from topology and cohomology. A (cen…
Decomposition theorems for a generalization of the holonomy Lie algebra of an arrangement
Clas Löfwall
In [7, Papadima and Suciu, When does the associated graded Lie algebra of an arrangement group decompose? Comment. Math. Helv. {\bf 81:4} (2006), 859--875] it is proved that the ho…
Solvable Infinite Filiform Lie Algebras
Clas Löfwall
An infinite filiform Lie algebra L is residually nilpotent and its graded associated with respect to the lower central series has smallest possible dimension in each degree but is…
