%O Bibliogr.: 8. p. ; ĂśsszefoglalĂĄs angol nyelven %D 2021 %T Optimal version of the Picard-LindelĂśf theorem %X Consider the differential equation y 0 = F(x, y). We determine the weakest possible upper bound on |F(x, y) â F(x, z)| which guarantees that this equation has for all initial values a unique solution, which exists globally. %A Schlage-Puchta Jan-Christoph %N 39 %K DifferenciĂĄlegyenletek - kĂśzĂśnsĂŠges, Picard-LindelĂśf tĂŠtel %L acta73691
