We show that ifD= {(x,y): 0 <x< 1,f(x) <y< 1}, wherefis negative, upper semicontinuous, and bounded below, then the semigroup associated with the Dirichlet Laplacian onDis intrinsically ultracontractive. Analogs in higher dimensions are proved. We construct domains of infinite area with this property.
