Witryna13 kwi 2024 · The scalar field, chosen as a vector (5-component) representation, turns out to be proportional to the radial vector of S4. The whole system is regular … WitrynaIn fluid dynamics, irrotational lamellar fields have a scalar potential only in the special case when it is a Laplacian field. Certain aspects of the nuclear force can be described by a Yukawa potential. The potential play a prominent role in the Lagrangian and Hamiltonian formulations of classical mechanics.
