We establish some comparison theorems on Finsler manifolds with curvature quadratic decay. As their applications, we obtain some optimal Cheeger-Gromo......

We show that if theta is an irrational number in [0, 1), theta(1) and theta(2) are in [0, 1), A = [GRAPHICS] is a matrix of infinite order in SL2(Z), ......

For a singular Riemannian foliation F on a Riemannian manifold, a curve is called horizontal if it meets the leaves of F perpendicularly. For a singul......

We study Lie bialgebroid crossed modules which are pairs of Lie algebroid crossed modules in duality that canonically give rise to Lie bialgebroids. A......

Given a crossed module of groupoids N -> G, we construct (1) a natural homomorphism from the product groupoid Zx (N (sic) G) paired right arrows N ......

It is shown that except in three cases conjugacy classes of classical Weyl groups W(Bn) and W(D-n) are of type D. This proves that Nichols algebras of......

In this paper, we first construct a symplectic Schur function solution to a newly defined two-component symplectic Kadomtsev-Petviashvili hierarchy. A......

We consider a problem of whether a property of holomorphic curves on a subset X of the complex plane can be extended to the whole complex plane. In th......
