Query: Wall-crossing and recursion formulae for tropical Jucys covers   In recent work, the authors derived a tropical interpretation of monotone and
strictly monotone double Hurwitz numbers. In this paper, we apply the technique
of tropical flows to this interpretation in order to provide a new proof of the
piecewise polynomiality of these enumerative invariants. Moreover, we derive
new types of wall-crossing formulae.
