We derive the limit shape of Young diagrams, associated with growing integer partitions, with respect to multiplicative probability measures underpinned by the generating functions of the form ℱ(z)=∏ℓ=1∞ℱ0(zℓ) (which entails equal weighting among possible parts ℓ∈ℕ ). Under mild technical assumptions on the function H0(u)=ln(ℱ0(u)) , we show that the limit shape ω*(x) exists and is given by the equation y=γ−1H0(e−γx) , where γ2=∫01u−1H0(u) du . The wide class of partition measures covered by…
