Mathieu-rk-apr30tex 3 after an initial transient, the numerical solutions approach asymptotic states which are independent of initial conditions. Quasi-periodic mathieu equation 197 the title of this paper is explained by noting that equation (1) may be viewed as an oscillator with natural frequency.
Time-delay two-dimension mathieu equation in synchrotron 501 they studied a system consisting of a train of two particles which is modeled as two coupled nonlinear mathieu equations with delay coupling. In the particular case of mathieu equations, one proves that the transition from stability to instability occurs when both eigenvalues are equal to 1 or both equal to in other words.
Based on some recent progress on a relation between four dimensional super yang-mills gauge theory and quantum integrable system, we study the asymptotic spectrum of the quantum mechanical problems described by the mathieu equation and the lamé equation the large momentum asymptotic expansion of the eigenvalue is related to the instanton.

Which exist only when the point in the parameter plane lies on the boundary of the stability zones a mathieu function is even or odd, and is unique up to a factor the second linearly-independent solution grows linearly in for , provided the even mathieu functions are the eigen functions of the integral equation. Mathieu sine and cosine for fixed a,q, the mathieu cosine is a function of defined as the unique solution of the mathieu equation which takes the value , is an even function, hence similarly, the mathieu sine is the unique solution which takes the value , is an odd function, hence these are real-valued functions which are closely. The mathieu equation is a linear second-order differential equation with periodic coefficients floquet theory is a branch of the theory of ordinary differential equations relating to the class of solutions to linear differential equations of the form. On the other hand, an analytical solution of mathieu equation has also the mathematical theoretical aspect it is determined by the fact that the solution of a num-ber of diﬀerential equations is reduced to the solution of mathieu equation they, for example, are 1.
