We present a construction of divergence-free and curl-free wavelets on the square, that could satisfy suitable boundary conditions. This construction is based on the existence of biorthogonal multiresolution analyses (BMRA) on [0, 1], linked by differentiation and integration. We introduce new BMR...
The first method is a cut finite element discretization of the Stokes equations based on the Brezzi–Douglas–Marini (BDM) elements and involves interior penalty terms to enforce tangential continuity of the velocity at interior edges in the mesh. The second method is a cut finite element ...

Again the divergence theorem is confirmed. ▪ Example 7.4.3 Function that Vanishes on Boundary The divergence theorem is often used in situations where a function vanishes on the boundary of the region involved. Here we apply the theorem to F=exp(-r2)r over the entire 3-D space to ...
Divergence & Curl of Vector: The divergence of a vector is a scalar quantity that gives the expansion of the flow at a certain point. It has nothing to do with direction. The divergence of a vector is equal to the scalar product of nabla {eq}(\vec\nabla...
A Helmholtz identity is used to prove two three-vector uniqueness theorems in Euclidean three-space. The first theorem specifies the divergence and curl of... Woodside,A Dale - 《American Journal of Physics》 被引量: 16发表: 2009年

Calculate the curl and the divergence of the following vector fields vec(F)and vec(H),respectively. If the curl turns out to be zero, try to discover a scalar functionφof which the vector field is the gradient(e.g.gra...
arrow above) = 0 if and only if A(combining right arrow above) = grad φ if A = grad φ, then the line integral does not depend on path; and if the line integral of a vector function is equal to zero for any closed path, then this vector is the gradient of a scalar function....
