Abstract
A perspective on the connections between linear and branched polymer θ collapses in two dimensions is provided by a vesicle model with vacancies. Percolation geometry plays simultaneously key roles in determining the multicritical properties of both problems. For branched polymers, besides two distinct θ lines, a transition between different collapsed regimes and several exponents are exactly obtained. Universality issues are also discussed.Keywords
