Regular Submanifolds in the Conformal Space {mathbb Q}^n_p

There is a Lorenzian group acting on the conformal space ${\mathbb Q}^n_p$. We study the regular submanifolds in the conformal space ${\mathbb Q}^n_p$ and construct general submanifold theory in the conformal space ${\mathbb Q}^n_p$. Finally we give the first variation formula of the Willmore volume functional of submanifolds in the conformal space ${\mathbb Q}^n_p$ and classify the conformal isotropic submanifolds in the conformal space ${\mathbb Q}^n_p$.
