self-oscillatory motion, The derived period equations determine

From the Fourier series one can pass to the closed form of the
ele-
ments of the column matrix which are roots of the characteristic
polynomial N(p), There are 6 Soviet-bloc references.

TEXT: The author studies the system of equations

is a square matrix of constants; X(t) is the column
of unknowns. A column X(t,T) is introduced, coinciding with
the required solution in the interval + 0 --'- t < x - 0, and
zero outside this interval over the entire t-axis. x(t,x) will
be considered as the value of the unsymmetrical, periodic
column X,(t,T) with period 'r within the interval
