Global representations of the conformal group and eigenspaces of the Yamabe operator on $S^1 \times S^n$

Mark R. Sepanski and Jose A. Franco

Vol. 275 (2015), No. 2, 463–480
Abstract

Using parabolic induction, a global representation of a double cover of the conformal group SO(2,n + 1)0 is constructed. Its space of finite vectors is realized as a direct sum of eigenspaces of the Yamabe operator on S1 × Sn. The explicit form of the corresponding eigenvalues is obtained. An explicit basis of K-finite eigenvectors is used to study its structure as a representation of the Lie algebra of the conformal group.
