Let Ω ⊂ R n be a bounded domain, and for x ∈ Ω let τ (x) be the expected exit time from Ω of a diffusing particle starting at x and advected by an incompressible flow u. We are interested in the question which flows maximize τ L ∞ (Ω) , that is, they are most efficient in the creation of hotspots inside Ω. Surprisingly, among all simply connected domains in(More)
