Frobenius splitting and geometry of -Schubert varieties
Xuhua He, Jesper Funch Thomsen
Let be an equivariant embedding of a connected reductive group over an algebraically closed field of positive characteristic. Let denote a Borel subgroup of . A…
Geometry of -orbit closures in equivariant embeddings
Xuhua He, Jesper Funch Thomsen
Let denote an equivariant embedding of a connected reductive group over an algebraically closed field . Let denote a Borel subgroup of and let denote a $B \t…
Closures of Steinberg fibers in twisted wonderful compactifications
Xuhua He, Jesper Funch Thomsen
By a case-free approach we give a precise description of the closure of a Steinberg fiber within a twisted wonderful compactification of a simple linear algebraic group. In the non…
Frobenius splitting of equivariant closures of regular conjugacy classes
Jesper Funch Thomsen
Let denote a connected semisimple and simply connected algebraic group over an algebraically closed field of positive characteristic and let denote a regular element of…
F-regularity of large Schubert varieties
Michel Brion, Jesper Funch Thomsen
Let G denote a connected reductive algebraic group over an algebraically closed field k and let X denote a projective G x G-equivariant embedding of G. The large Schubert varieties…
A new realization of the cohomology of Springer fibers
Shrawan Kumar, Jesper Funch Thomsen
In this note we give a geometric realization of the cohomology of Springer fibers in type A. More precisely, we describe the cohomology by the coordinate ring of a scheme theoretic…
