            ``Invariant Manifolds for Steady Boltzmann Equation.''

＜研究発表要旨＞
The invariant manifolds for the steady Boltzmann equation are constructed. 
For the case of non-resonance, the construction is based on the Green's 
function approach. At the resonance cases when the Mach number at the 
far field is near zero or one, there are the wave patterns containing 
the  Knudsen-type layers and fluid-like waves, and singular bifurcations
occur. Because of the infinite dimensional nature of the Boltzmann 
equation, there are new elements besides the center manifold theory for 
the differential equations.
