WebA region R is called simply connectedif every closed loop in R can continuously be pulled together within R to a point inside R. If curl(F~) = 0 in a simply connected region G, then F~ is a gradient ﬁeld. Proof. Given aclosed curve C in Genclosing aregionR. Green’s theorem assures that R C F~ dr~ = 0. So F~ has the closed loop property in G. In vector calculus, Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C. It is the two-dimensional special case of Stokes' theorem.
