Homeomorphism Classification of positively curved manifolds with almost maximal symmetry rank
Fuquan Fang, Xiaochun Rong
We show that a closed simply connected 8-manifold (9-manifold) of positive sectional curvature on which a 3-torus (4-torus) acts isometrically is homeomorphic to a sphere, a comple…
Inflationary attractor property of phantoms
Xin-He Meng, Peng Wang
There are some motivations to consider inflation driven by a phantom field. Before entering into some specific models and perform data fitting, it is important first investigating…
The naturally designed spherical symmetry in the genetic code
Chi Ming Yang
In the present work, 16 genetic code doublets and their cognate amino acids in the genetic code are fitted into a polyhedron model. Based on the structural regularity in nucleobase…
Circle actions and Z/k-manifolds
Weiping Zhang
We establish an S^1-equivariant index theorem for Dirac operators on Z/k-manifolds. As an application, we generalize the Atiyah-Hirzebruch vanishing theorem for S^1-actions on clos…
Chiral Condensates in Quark and nuclear Matter
G. X. Peng, U. Lombardo, M. Loewe +2
We present a novel treatment for calculating the in-medium quark condensates. The advantage of this approach is that one does not need to make further assumptions on the derivative…
Index iteration theory for symplectic paths with applications to nonlinear Hamiltonian systems
Yiming Long
In recent years, we have established the iteration theory of the index for symplectic matrix paths and applied it to periodic solution problems of nonlinear Hamiltonian systems. Th…
