On a Liu–Yau type inequality for surfaces

Then Szabo [Sz] constructed pairs of isospectral compact manifolds with boundary that are not locally isometric, and Gordon and Wilson [GW3] generalized his construction to

In 1994, they also considered submanifolds of a Riemannian manifold and obtained the equations of Gauss, Codazzi and Ricci associated with a semi-symmetric non-metric connection

Our results are based on center manifold theory for quasilinear parabolic equations and on equivariant bifurcation theory for not necessarily self-similar solutions of a

Since we are motivated by applications to nonlinear PDEs involving vector fields, we present our result in the context of a sub-Laplacian operator: a finite sum of square of

In this paper, motivated by the above works, we shall investigate a class of (open) Riemannian manifolds of asymptotically nonnegative curvature (after Abresch [1])). To be precise,

L’accès aux archives de la revue « Annali della Scuola Normale Superiore di Pisa, Classe di Scienze » ( http://www.sns.it/it/edizioni/riviste/annaliscienze/ ) implique l’accord

Since all toric surfaces arise from consecutive equivariant blowups of either C P 2 or one of the the Hirzebruch surfaces F a and how the weights on the weighted circular graph
