what does this kind of notation mean

is that saying that the line will start at point T and end at point T? and how do i perform such integrations for example:

### Re: contour integral notation

Hi;

Last time I used contour integration was for an asymptotic expansion of a generating function. I needed to raise a polynomial to a large power and needed to get a specific coefficient. Looking at my notes I can hardly understand any of it.

Try these pages, if you cannot get any of this then you need to beef up your complex analysis and calculus. Sorry, couldn't be more help.

Lots of examples are here.

In mathematics, you don't understand things. You just get used to them.

### Re: contour integral notation

It is an integral,an integral wich is resoklved as an normal integral,as I know.
It is used to integral circular surfaces.
It is like the Gauss law in electrostatic
