Photoshop CC 2020 tutorial showing how to create vexel art portraits from photos. The term, "vexel" is a combination of the words, "Vector" and "Pixel". Vexel art is an entirely pixel-based, raster ...

In the present paper we introduce eigenfunctions of the curl operator. The expansion of vector fields in terms of these eigenfunctions leads to a decomposition of such fields into three modes, one of ...

We study the displacement map associated to small one-parameter polynomial unfoldings of polynomial Hamiltonian vector fields on the plane. Its leading term, the generating function M(t), has an ...
