2k-Einstein结构的形变

Deformations of 2k-Einstein structures

Levi Lopes de Lima, Newton Luis Santos

摘要:

证明了在紧致非平坦空间型下,2k-爱因斯坦结构的无穷小形变空间是有限维的。此外,球面空间型被证明是刚性的,因为它们在相应的模空间中是孤立的。

英文摘要:

It is shown that the space of infinitesimal deformations of 2k-Einstein structures is finite dimensional at compact non-flat space forms. Moreover, spherical space forms are shown to be rigid in the sense that they are isolated in the corresponding moduli space.
