Singular Poisson-Kaehler geometry of Scorza varieties and their secant varieties
Johannes Huebschmann
Each Scorza variety and its secant varieties in the ambient projective space are identified, in the realm of singular Poisson-Kaehler geometry, in terms of projectivizations of hol…
Stratified Kaehler structures on adjoint quotients
Johannes Huebschmann
Given a compact Lie group, endowed with a bi-invariant Riemannian metric, its complexification inherits a Kaehler structure having twice the kinetic energy of the metric as its pot…
Relative homological algebra, equivariant de Rham theory, and Koszul duality
Johannes Huebschmann
Let G be a general (not necessarily finite dimensional compact) Lie group, let g be its Lie algebra, let Cg be the cone on g in the category of differential graded Lie algebras, an…
Homological perturbations, equivariant cohomology, and Koszul duality
Johannes Huebschmann
Our main objective is to demonstrate how homological perturbation theory (HPT) results over the last 40 years immediately or with little extra work give some of the Koszul duality…
