In this paper we study the existence and non-existence of minimizers for a\ntype of (critical) Poincar 'e-Sobolev inequalities. We show that minimizers\ndo exist for smooth domains in \ℝd, an also for some polyhedral\ndomains. On the other hand, we prove the non-existence of minimizers in the\nrectangular isosceles triangle in \ℝ2.\n
