WebMay 29, 2024 · Can I apply the gradient theorem for a field with not simply connected domain? Let $ \pmb G $ be a vector field with domain $ U \subseteq \mathbb{R^2}. $ If $ U $ is not simply connected, but there exists a function $ f $ such that $ \pmb G = \pmb \nabla f \; \; \forall \; (x,y)... WebBy "multiple connected" you probably mean "not simply connected", and of course you cannot conclude that those integrals all vanish. A function with a simple pole at the origin is analytic in an annulus around the origin, and the integral over any simple closed cycle within the annulus that winds once around the origin will be nonzero (indeed, it will have the …
WebOct 20, 2015 · $\begingroup$ In 2D you can work with somewhat less sophisticated methods by thinking about complex analysis. Basically, if you have a simply connected domain, a closed path in that domain, and a holomorphic function on the domain, then you can homotopically contract the path to a point. WebGreen's Theorem. Let C be a simple closed curve in the plane that bounds a region R with C oriented in such a way that when walking along C in the direction of its orientation, the region R is on our left. Suppose that F = F 1, F 2 is vector field with continuous partial derivatives on the region R and its boundary . C.

It is a path-connected set … WebMar 9, 2012 · Second, if the polynomial representing the ellipse appeared to a negative power in the Dulac function, then we cannot apply Green's theorem since the region surrounding the ellipse is not simply connected. This can be overcome in certain cases by considering line integrals around the loop itself.
