Path integral and line integrals

Click For Summary
SUMMARY

The discussion clarifies the distinction between path integrals and line integrals in mathematics and physics. A line integral typically integrates a vector function along a curve with respect to arc length, while a path integral, particularly in quantum mechanics, sums over all possible paths. The key takeaway is that while both integrals can refer to similar concepts in certain contexts, their applications and definitions diverge significantly, especially in quantum mechanics.

The Attempt at a Solution



is path integral over a scalar function

and line integral is over vector function?


I'm confused about this pls help me understand

thanks in advance

they can quite often be used to refer to the same thing, see
http://en.wikipedia.org/wiki/Line_integral

they basically integrate the function along the curve with repsect to arc length

as the integral is with repsect to arc length it is independent of parameterisation

also different is the path integral in quantum mechanics which is a sum over all possible paths
