【摘要】 对解析函数f(z)=p(z)/q(z),当z=a分别是p(z)和q(z)的m级零点和n级零点,且0≤m<n时,特别地n=m+2时,讨论了求f(z)在极点z=a处留数的方法并举例说明其应用.更多还原

【Abstract】 A method for residue of the function f(z)= p(z)/q(z)at the isolated singular point z=ais discussed.Here p(z)has the zero of order m and q(z)has the zero of order n respectively at z=a,and 0≤m <n,in particular n=m+2.更多还原
