Universal Bounds for Eigenvalues of the Polyharmonic Operators
Jürgen Jost, Xianqing Li-Jost, Qiaoling Wang +1
We study eigenvalues of polyharmonic operators on compact Riemannian manifolds with boundary (possibly empty). In particular, we prove a universal inequality for the eigenvalues of…

Universal Inequalities for Eigenvalues of the Buckling Problem of Arbitrary Order
Jürgen Jost, Xianqing Li-Jost, Qiaoling Wang +1
We investigate the eigenvalues of the buckling problem of arbitrary order on compact domains in Euclidean spaces and spheres. We obtain universal bounds for the th eigenvalue in…

A Note on Quantum Entanglement and PPT
Shao-Ming Fei, Xianqing Li-Jost
We study quantum states for which the PPT criterion is both sufficient and necessary for separability. We present a class of 3x3 bipartite mixed states and show that these states a…
