The Linear Time-varying State Space Model(LTM) is one of important system models in engineering. The purpose of this report is to present a new computational algorithm for solving minimum norm control problems of LTM. The new algorithm is based on the small gain theorem. The justificability of the new approach is illustrated by some examples.

Squire's theorem is fundamental in a fluid stability theory. This theorem asserts that in a parallel flow, the critical Reynolds number for 3-dimensional (3-D) disturbances is always greater than that for 2-D disturbances. This report attempts to give a proof of Squire's theorem in a constructive approach. A process of the proof itself gives a method of a stability analysis for 2-D parallel flows. The stability of fundamental flows, I. e. a plane Poiseuille flow and a Couette flow, are invenstigated by the method. These results give a good agreement with previous one.
