New class of symmetries for self-gravitating hydrodynamics equations
Souichi Murata, Kazuhiro Nozaki
A method of calculating a new class of symmetries is presented for partial differential equations. The method give a new dynamical solution for an isothermal and cylindrically symm…

Asymptotic expansions of unstable (stable) manifolds in time-discrete systems
Shin-itiro Goto, Kazuhiro Nozaki
By means of an updated renormalization method, we construct asymptotic expansions for unstable manifolds of hyperbolic fixed points in the double-well map and the dissipative Hénon…
