    Integration of double derivative

    Hello everyone!

    I'm seeking help for resolving this integral where gamma is a constant and Z(s) is a continuous function of s.

    <br />
\frac{1}{\gamma} \int_t^T e^{-\gamma(T-s)}\ \frac{d^2}{d s^2}\ln(Z(s))\ ds<br />

    Any help will be greatly appreciated!

    Thanks in advance,
    Paolo

    There is not way of doing this without knowning Z(s). Using integration by parts twice we can get \int e^{-\gamma (T-s)}\ln Z(s) ds.
