Abstract: We show that there exist generic slow-fast systems with only onetime-scaling parameter on the two-torus, which have canard cycles forarbitrary small values of this parameter. This is in drastic contrast with theplanar case, where canards usually occur in two-parametric families. Here wetreat systems with a convex slow curve. In this case there is a set ofparameter values accumulating to zero for which the system has exactly oneattracting and one repelling canard cycle. The basin of the attracting cycle isalmost the whole torus.
