Stokes’ theorem relates a vector surface integral over surface S in space to a line integral around the boundary of S. Therefore, just as the theorems before it, Stokes’ theorem can be used to reduce an integral over a geometric object S to an integral over the boundary of S.

Stokes' theorem, also known as Kelvin–Stokes theorem after Lord Kelvin and George Stokes, the fundamental theorem for curls or simply the curl theorem, is a theorem in vector calculus on R 3 {\displaystyle \mathbb {R} ^{3}}.

As above, this can be used to derive a physical interpretation of ∇·F: CLOSED AND EXACT FORMS - Line and Surface Integrals; Differential Forms and Stokes Theorem - Beginning with a discussion of Euclidean space and linear mappings, Professor Edwards (University of Georgia) follows with a thorough and detailed exposition of multivariable differential and integral calculus. Among the topics covered are the basics of single-variable differential calculus generalized Lecture 38: Stokes’ Theorem As mentioned in the previous lecture Stokes’ theorem is an extension of Green’s theorem to surfaces. Green’s theorem which relates a double integral to a line integral states that RR D ‡ @N @x ¡ @M @y · dxdy = H C Mdx+Ndy where D is a plane region enclosed by a simple closed curve C. Stokes’ theorem 31. Stokes Theorem Stokes’ theorem is to Green’s theorem, for the work done, as the divergence theorem is to Green’s theorem, for the ux. Both are 3D generalisations of 2D theorems.

Stokes’ Theorem ex-presses the integral of a vector ﬁeld F around a closed curve as a surface integral of another vector ﬁeld, called the curl of F. This vector ﬁeld is constructed in the proof of the theorem. Once we have it, we in-vent the notation rF in order to remember how to compute it. 22. 1.
