主要观点The Lp dual curvature measures were recently introduced by Lutwak et al. (Adv Math 329:85-132, 2018) to unify the classical theory of mixed volumes and the newer theory of dual mixed volumes of convex bodies. However, the associated Lp dual Minkowski problems for many important special cases remain open problems. They are analytically equivalent to a class of nonlinear problems with indices p and q. In most previous studies, conventional geometric inequalities and Aleksandrov's variational formula for convex bodies were used to study these problems.  In this paper, by using a new investigation method via directly studying the nonlinear problems characterizing the planar Lp dual Minkowski problem in Sobolev spaces, several sharp functional inequalities associated with the Lp dual curvature measures are established to generalize the classical inequalities, such as the Wirtinger's inequality and the Blaschke-Santal\'{o} inequality. Based on these new sharp functional inequalities, various existence results for the planar Lp dual Minkowski problem are obtained for integrable data and general. Compared with the uniqueness results of periodic solutions for  and  (in Dohmen and Giga, Proc Japan Acad Ser A Math Sci, 1994; Andrews, J Amer Math Soc, 2003), the non-uniqueness and multiple periodic solutions are also obtained in this paper for  and all  through variational analysis.
