Time-like isothermic surfaces associated to Grassmannian systems

Doc. Math., J. DMV 10, 527-549 (2005)

Summary

Summary: We establish that, as is the case with space-like isothermic surfaces, time-like isothermic surfaces in pseudo-riemannian space $\mathbb R^{n-j,j}$ are associated to the $O(n-j+1,j+1)/O(n-j,j)\times O(1,1)$-system.
