摘要:Abstract(#br)Let G be a split simple affine algebraic group of type A or C over a field k , and let E be a standard generic G -torsor over a field extension of k . We compute the Chow ring of the variety of Borel subgroups of G (also called the variety of complete flags of G ), t...

摘要:Abstract(#br)We introduce a Hopf algebra structure of subword complexes, including both finite and infinite types. We present an explicit cancellation free formula for the antipode using acyclic orientations of certain graphs, and show that this Hopf algebra induces a natural non...

摘要:Abstract(#br)It has been known since the work of Duskin and Pelletier four decades ago that K op , the opposite of the category of compact Hausdorff spaces and continuous maps, is monadic over the category of sets. It follows that K op is equivalent to a possibly infinitary ...

摘要:Abstract(#br)Motivated by the challenge of defining twisted quantum field theories in the context of higher categories, we develop a general framework for lax and oplax transformations and their higher analogs between strong ( ∞ , n ) -functors. We construct a double ( ∞ , n...

摘要:Abstract(#br)We prove that if ϕ : ( X , 0 ) → ( X , 0 ) is a finite endomorphism of an isolated singularity such that deg ⁡ ( ϕ ) ≥ 2 and ϕ is étale in codimension 1, then X is Q -Gorenstein and log canonical.

摘要:Abstract(#br)Much has been written about expansions of real numbers in noninteger bases. Particularly, for a finite alphabet { 0 , 1 , … , α } and a real number (base) 1 < β < α + 1 , the so-called univoque set of numbers which have a unique expansion in base β has garn...

摘要:Abstract(#br)The main problem studied here is resolution of singularities of the cotangent sheaf of a complex- or real-analytic space X 0 (or of an algebraic variety X 0 over a field of characteristic zero). Given X 0 , we ask whether there is a global resolution of singular...

摘要:Abstract(#br)We classify finite-dimensional tame modules over the ortho-symplectic Lie superalgebras. For these modules we show that their characters are given by the Kac–Wakimoto character formula, thus establishing the Kac–Wakimoto conjecture for the ortho-symplectic Lie s...

摘要:Abstract(#br)Given a class of closed Riemannian manifolds with prescribed geometric conditions, we introduce an embedding of the manifolds into ℓ 2 based on the heat kernel of the Connection Laplacian associated with the Levi-Civita connection on the tangent bundle. As a res...

摘要:Abstract(#br)Dimension conservation for almost every projection has been well-established by the work of Marstrand, Mattila and Hunt and Kaloshin. More recently, Hochman and Shmerkin used CP-chains, a tool first introduced by Furstenberg, to prove all projections preserve di...
