Hamilton-Souplet-Zhang's gradient estimates for two types of nonlinear parabolic equations under the Ricci flow
In this paper, we consider gradient estimates for two type of nonlinear
parabolic equations under the Ricci flow: one is the equation with two real constants, the other is with two real constants. By a suitable
scaling for the above two equations, we obtain Hamilton-Souplet-Zhang type
gradient estimates.Comment: All comments are welcom
Eigenvalue estimates for the higher order buckling problem
In this paper, we consider lower order eigenvalues of Laplacian operator with
any order in Euclidean domains. By choosing special rectangular coordinates, we
obtain two estimates for lower order eigenvalues.Comment: This article has an erro
