Peskin equ(2.51)and(2.52)

    1. The problem statement, all variables and given/known data
    can we use the Steepest descent method,formula is in the picture
    2. Relevant equations
    for the case of picture one it has AN APPROXIMATE EXPRESSION in picture two.
    3. The attempt at a solution
    for (2.51),h(z)=-iz,z_{0}=m(mass),m=1,n=0;it caulate e^{-imt}/t,take the limit
    t->\infty,the result is 0
    for (2.52),h(z)=-z,z_{0}=m(mass),m=1,n=0;it caulate e^{-imt}/t,take the limit
    t->\infty,the result is 0
    where is wrong?
