On ordinary differential equations in Fréchet spaces. (Über gewöhnliche Differentialgleichungen in Frécheträumen.) (German) Zbl 0832.34055
Karlsruhe: Math. Fak., Univ. Karlsruhe, 65 S. (1992).
Let \(F\) be a real Fréchet space and denote by \(f: [0, T]\times F\to F\) a continuous mapping. The author considers the initial value problem \((*)\) \(y'(t)= f(t, y(t))\), \(y(0)= y_0\in F\) in \(F\) and investigates the existence and non-existence as well as the uniqueness problems to \((*)\). The difference to corresponding results in the Banach space case is pointed out.
