Shinichi Tajima and Yayoi Nakamura, Algebraic local cohomology classes attached to quasi-homogeneous hyper- surface isolated singularities

Projection of Differential Algebras and Elimination As was indicated in 5.23, Proposition 5.22 ensures that if we know how to resolve simple basic objects, then a sequence of

Given a second order elliptic dierential operator L on a com- pact C 1 manifold, we prove that the group of transformations which preserve the sheaf of functions annuled by L is a

It is shown that an isolated singularity is quasi-homogeneous if and only if an algebraic local cohomology class generating the dual space can be characterized as a solution of

If one wants to see more explicitly how a canonical A ∞ -structure on A L looks like, one has to choose one of the natural dg-algebras with cohomology A L (an obvious algebraic

163–169] observed that to any complex supermanifold, there will be associated a hierarchy of inductively defined cohomology classes representing obstructions to the existence of

Nicolaescu and the author formulated a conjecture which relates the geometric genus of a complex analytic normal surface singularity (X, 0) — whose link M is a rational homology

Definition 3.1 ([2], [3]). If a normal surface singularity is obtained in this way, then it is called a Kodaira singularity of genus g. maximal ideal) cycle on the minimal resolution
