What does an integral symbol with a circle mean?
2015年12月31日 · The usual usage of the $ \unicode{x222e}~$ symbol in Mathematics denotes an integral over a closed line. The traditional symbols for integrals over closed surfaces or volumes $^{(*)}$ were $ \unicode{x222F}~$ and $ \unicode{x2230}$. However, different usages can be found in Physics.
What is an integral with a circle through it? - Physics Forums
2009年9月13日 · In summary, an integral with a circle through it is a symbol used in mathematics to represent a contour integral, which integrates a complex-valued function along a given curve in the complex plane. It differs from a regular integral in that it integrates over a path or curve in the complex plane rather than over a range of real numbers.
The Mysterious Name of the Integral Symbol: A Mystery Solved?
2004年12月6日 · The integral symbol was first used by Swiss mathematician Johann Bernoulli in 1696. However, it was later refined by mathematician Gottfried Leibniz in 1705 and is often referred to as the "Leibniz integral symbol".

What does the circle in the integral sign signify? - Physics Forums
2003年11月8日 · A line integral is performed over a one-dimensional subspace of the domain, while a "normal" integral may not cover the entire domain. The "normal" integral is a special case of a line integral where the path is restricted to the x-axis. The \oint symbol can be replaced with \int without changing its meaning.
