| Abstract: | In this paper, We discussed the limit-circle classification for system of Variable Coefficient linear differential equations
By method of Variation of Constants, W e obtained a few sufficient Conditions that equation( 1 )is limit-Circle In the special case, We obtained Criterions that equation
(r(t)x'(t))'+q(t)x(t)= 0 is limit-circle. |
