Discussion In this article, we have introduced a testable criterion for robustness for a given cycle of heteroclinic con- nections within constrained settings—this test involves finding the connection ... C 1 perturbations in X . The HC may, however, be robust to a constrained set of perturbations. We explore this in the following sections. 2.1 Conditions for robustness...

... 13, 1994. Abstract. Bounds on the number of simple zeros of the derivatives of a function are used to give bounds on the number of distinct zeros of the function. The Riemann ξ-function is defined ... generically, the left side of (7) equals N (j) s (T ). In other words, the zeros of the derivatives of a generic function are all simple, except for thos...
