WebMar 29, 2014 · In 2D, the dual to a bivector is a scalar. In 3D, the dual to a bivector is a vector. Typically, students learn only about the vector, because bivectors are not typically taught. So to answer your question: the curl in 2D is definitely not a vector. If you think of the 3D curl as a vector, you should think of the 2D curl as a scalar. Mar 28, 2014 WebCurl of 2d vector field?

In order to compute the curl of vector V(u,v) i did it like so: ... WebThe curl in 2D is sometimes called rot: rot ( u) = ∂ u 2 ∂ x 1 − ∂ u 1 ∂ x 2. You can also get it by thinking of the 2D field embedded into 3D, and then the curl is in z direction, that is, it only has one component. As you rightly say, it is in essence the same as the div: div ( u) = rot ( u ⊥), where u ⊥ = ( − u 2, u 1). how are homeless people marginalizedWebJan 14, 2024 · In two-dimensions, the curl is a scalar, not a vector field itself. To get a completely general description of the concept of curl, you need differential forms, but this a relatively complex matter. Another way to see it is that your expression is the z-component of the 3-dimensional curl for a vector field which does not depend on the z-direction. how are homeowners insurance rates calculated
