This paper is a continuation of recent work by Guo-Xiang-Zheng[10].We deduce the sharp Morrey regularity theory for weak solutions to the fourth order nonhomogeneous Lamm-Rivière equation△2u=△(V▽u)+div(w▽u)+(▽ω+F)·▽u+f in B4,under the smallest regularity assumptions of V,(w),ω,F,where f belongs to some Morrey spaces.This work was motivated by many geometrical problems such as the flow of bihar-monic mappings.Our results deepens the Lp type regularity theory of[10],and generalizes the work of Du,Kang and Wang[4]on a second order problem to our fourth order problems.
