Abstract

For p(,0)(0,1)p\in (-\infty,0)\cup(0,1) and a convex body KRnK\subset\mathbb{R}^n with the origin in its interior, we construct the family of pp-affine dual curvature measures Ip(K,)\mathcal{I}_p(K,\cdot) with respect to KK. The affine-invariant measure C~n1a(K,)\widetilde{C}_{n-1}^{\mathrm{a}}(K, \cdot) given in the paper [9] is the limit case of Ip(K,)\mathcal{I}_p(K,\cdot) as p1p\rightarrow 1^-. The classical cone-volume measure is the limit case of the affine measures 2pIp(K,)/(n2V(IpK))2|p|\mathcal{I}_p(K,\cdot)/(n^2V(\mathrm{I}_pK)) when p0p\rightarrow 0 and V(K)=2V(K)=2, where IpK\mathrm{I}_pK denotes the LpL_p intersection body of KK. The Minkowski problems for the pp-affine dual curvature measures are proposed and studied. Specifically, we give a sufficient condition for the existence of a solution to the even Minkowski problem for pp-affine dual curvature measure. Moreover, a necessary condition is given when p(0,1)p\in (0,1). The smooth case of this Minkowski problem is equivalent to solving a new type of partial differential equations with respect to pp-cosine transforms.
