By resorting to the residue method,The basic properties of eigenvalue problem and the expansion theorem of the Dirac equation B(?)+ P(x)y-λy with boundary conditions y2(0) =0,ay1(π) +λy2(π) = 0 are proved.Let B = (?), p(x)and r(x)are real continuous function.first,the existence and the numeral of eigenvalue aer proved by the zero point existence ofentire function t[φ] then.we can prove the expansion theorem by the residue method. |
