Multisummability of formal solutions of some linear partial differential equations. (English) Zbl 1020.35018
The author treats formal power series solutions $$\widetilde u(t,x)= \sum^\infty_{n=1} u_n(x)t^n$$ of a linear partial differential equation in $$\mathbb{C}^{d+1}$$ $P(t,x,\partial_t,\partial_x) u(t,x)=f(t,x),\;(t,x)\in \mathbb{C}\times \mathbb{C}^d.$ {}.
