aRegarding both students' solutions of the problems as well as their concept maps in both series we see that Simone seems to have understood the fraction topic even before fraction teaching had begun in school whereas Stefan shows hardly any understanding after instruction as well as before. What...
We study the existence and uniqueness of C 1 + α -strict solutions for a general class of differential equations with state dependent delay. We also study the local well-posedness of this type of problems on subspaces of C 1 + α ( [ − p , 0 ] ; X ) . Some examples involving...
