Abstract

We prove local well-posedness of partially periodic and periodic modified KP-I equations, namely for tu+(1)l+12xlux1y2u+u2xu=0\partial_t u+(-1)^{\frac{l+1}{2}}\partial^l_x u-\partial_x^{-1}\partial_y^2 u+u^2\partial_x u=0 in the anisotropic Sobolev space Hs,s(R×T)H^{s,s}(\mathbb{R}\times \mathbb{T}) if l=3l=3 and s>2s>2, in Hs,s(T×T)H^{s,s}(\mathbb{T}\times \mathbb{T}) if l=3l=3 and s>198s>\frac{19}{8}, and in Hs,s(R×T)H^{s,s}(\mathbb{R}\times \mathbb{T}) if l=5l=5 and s>52s>\frac{5}{2}. All three results require the initial data to be small.
