Description
We examine several resummation methods for computing higher order corrections to the finite temperature effective potential, in the context of a scalar φ4 theory. We show by explicit calculation to four loops that dressing the propagator, not the vertex, of the one-loop tadpole correctly counts ''daisy'' and ''superdaisy'' diagrams
