On hypersurface quotient singularities of dimension 4
We consider geometrical problems on Gorenstein hypersurface orbifolds of dimension n ≥ 4 through the theory of Hilbert scheme of group orbits.
متن کاملCanonical Dimension
Canonical dimension is an integral-valued invariant of algebraic structures. We are mostly interested in understanding the canonical dimension of projective homogeneous varieties under semisimple affine algebraic groups over arbitrary fields. Known methods, results, applications, and open problems are reviewed, some new ones are provided. Mathematics Subject Classification (2010). Primary 14L17...
متن کاملDimension Reduction Based on Canonical Correlation
Dimension reduction is helpful and often necessary in exploring nonlinear or nonparametric regression structures with a large number of predictors. We consider using the canonical variables from the design space whose correlations with a spline basis in the response space are significant. The method can be viewed as a variant of sliced inverse regression (SIR) with simple slicing replaced by Bs...
متن کاملOn the number of crepant valuations of canonical singularities
In this note we calculate the number of crepant valuations of an isolated canonical singularity 0 ∈ X : (f = 0) ⊂ Cn, which is assumed to be nondegenerate with respect to its Newton polyhedron, in terms of weightings and the Newton polyhedron of f .
