      T. Y. Lam proposed abstracting algebraic properties of the Peirce corners eRe associated with an idempotent e in a ring R and introduced the notion of general corners. We consider this notion principally in the context of C*-algebras and some operator spaces in place of a ring R. Our aim is to characterise such corners as fully as we can,...

     We talk about some rigidity of self similar solutions for mean curvature flow and Kahler Ricci flow.

    Each locally compact group, commutative or not, (this includes finite groups and Lie groups) has a dual object which completely determines it. This object is a commutative semigroup which is partially ordered and convex. This duality theory generalizes the Pontryagin-Van Kampen duality for abelian, locally compact groups in a natural way. We...

    Based on a paper joint with David R. Adams, we will address quasi-continuities of Morrey potentials and their applications to fine properties of weak solutions of two p-Laplace systems: (p,q)-type harmonic map and Lane-Emden systems, whence getting that any local singular set of the minimizing p-harmonic maps from a bounded domain to the unit...

    I will discuss a sharp lower bound for the first positive eigenvalue of the sublaplacian on a closed, strictly pseudoconvex pseudo-hermitian manifold of dimension $2m+1\geq 5$. We prove that the equality holds iff the manifold is equivalent to the CR sphere up to a scaling. The essential step is a characterization of the CR sphere when there is a...

    Let M be a smooth hypersurface in R^{2n}. Suppose that on each side of M, there is a complex structure which is smooth up to M. Assume that the difference of the two complex structures is sufficiently small on M. We show that if a continuous function is holomorphic with respect to both complex structures, the function must be smooth from both...
