Al. Afendikov et Vp. Varin, DEGENERATE BIFURCATION GIVING RISE TO A CYCLE IN MULTIPARAMETER PROBLEMS IN HYDRODYNAMICS, Journal of applied mathematics and mechanics, 62(2), 1998, pp. 201-206
An algorithm for constructing the Lyapunov-Schmidt series in multipara
meter problems with quadratic non-linearity is proposed, which enables
a degenerate bifurcation of cycle generation to be investigated using
the Weierstrass preparation theorem. The use of this algorithm to stu
dy multiparameter problems of hydrodynamics, namely, Kolmogorov flow a
nd the Couette-Poiseuille flow in a plane channel is considered. (C) 1
