Yes, that's what I gathered. My eyes just don't like the block print for some reason.

Thanks. I also saw this article mathoverflow.net/questions/9898/…

Thank you, that's good too. I will have a think about this with respect to my work :-)

comment Notation for replacing a matrix column with a vector
Thanks, I was looking for something similar to this. I was going to use $A_j[v]$ before you answered my question.

@user227317 yes. See my answer for full details, but you got the answer! You can also use Blatter's approach too.

@user227317 no, as I said use the substitution $z=it$. Also @ JessicaK's solution will also work. See also @ ChrisrianBlatter's answer.

You need to parametrize the curve $\Gamma$, e.g. let $z(t)=it$ where $t\in[0,\pi/2]$. Looks like integration by parts may be helpful too.
