Later on, one can use this ‘degenerate’ case to construct examples where h is a true function instead of a measure. We shall not go back to this problem in the present paper. 3 Bouncing Back from the Singularity We shall begin our study of (2.1) by having a look at the solutions ...
In each iteration, the loop updates a set of variables\(\texttt {x}_i \in \mathcal {X}\). The right-hand-side of each assignment consists of polynomial expressions in the loop variables together with an (optional) nondeterministic noise term ...
