%0 Journal Article %T The H£żlder continuity of a class of 3-dimension ultraparabolic equations %A Wang Wendong %A Zhang Liqun %J Mathematics %D 2008 %I arXiv %X We obtained the $C^{\a}$ continuity for weak solutions of a class of ultraparabolic equations with measurable coefficients of the form $${\ptl_t u}= \ptl_x(a(x,y,t)\ptl_x u)+b_0(x,y,t)\ptl_x u+b(x,y,t)\ptl_y u,$$ which generalized our recent results on KFP equations. %U http://arxiv.org/abs/0808.4019v1
