Tropical differential equations
Siehe auch das Video dieses Vortrages.
Grigoriev introduced a theory of tropicalizing differential equations and their formal power series solutions over a trivially valued field. I will describe some generalizations of this theory and what kinds of information they are capable of detecting. In particular, I will explain how to extend to non-trivially valued coefficients and broader classes of series solutions, as well as a variation adapted to studying positive real solutions.
