SUMMARY

The discussion centers on the Maximal Solution Theorem in the context of differential equations, specifically examining the implications of continuity and local Lipschitz conditions on the function F: ℝ × Ω → E. It is established that if F is continuous and locally Lipschitz, the maximal solution (φ, J) diverges as the supremum of J approaches infinity. The inquiry raised is whether the same divergence holds if F is merely continuous, highlighting the critical role of the local Lipschitz condition for the uniqueness of local solutions.

Hello, I know a theorem that say that if ##F : \mathbb{R} \times \Omega \rightarrow E## is continuous and local lispchitziann in is seconde set value(where ##\Omega## is an open of a Banach space E.). we have that the maximum solution ##(\phi, J)##(where J is an open intervall and ##\phi : J \rightarrow \Omega## is ##C^{1}## .). of ##\phi'(t) = F(t, \phi(t))## diverge if ##sup(J) < + \infty##(##lim_{t \rightarrow sup(J)} \phi(t) = +\infty##.).

Is there the same results if F is just continuos please?

Thank you in advance and have a nice aftrenoon:oldbiggrin:.

Hello and thanks. In fact I recently knew that the local lipschitz condition is necessar for the uniqueness of a local solution to a diffential equation. I can give more if you want.
