$p$-adic families of Siegel modular cuspforms


Let $p$ be an odd prime and $g\geq 2$ an integer. We prove that a finite slope Siegel cuspidal eigenform of genus $g$ can be $p$-adically deformed over the $g$-dimensional weight space. The proof of this theorem relies on the construction of a family of sheaves of locally analytic overconvergent modular forms.
