We present and analyze a mixed finite element numerical scheme for the Cahn–Hilliard–Hele–Shaw equation, a modified Cahn–Hilliard equation coupled with the Darcy flow law. This numerical scheme was first reported in Feng and Wise (SIAM J Numer Anal 50:1320–1343, 2012 ), with the weak convergence to a weak solution … NettetRecalling that, for surfaces of Lorentz signatures the coderivative is δ = −⋆γ d⋆γ δ = − ⋆ γ d ⋆ γ we get the equation of motion δdXμ = 0 δ d X μ = 0.

Nettet12. sep. 2024 · This is the form taken by the general wave equation for our plane wave. Because the equations describe a wave traveling at some as-yet-unspecified speed c, we can assume the field components are each functions of x – ct for the wave traveling in the +x-direction, that is, \[E_y (x,t) = f(\xi) \, where \, \xi = x - ct. \label{16.21}\] NettetThe dependence of Maxwell's equation on the metric of spacetime lies in the Hodge star operator on 2-forms, which is conformally invariant. Written this way, Maxwell's equation is the same in any space–time, manifestly coordinate-invariant, and convenient to use (even in Minkowski space or Euclidean space and time, especially with curvilinear coordinates).
NettetHodge Conjecture. The answer to this conjecture determines how much of the topology of the solution set of a system of algebraic equations can be defined in terms of further algebraic equations. The Hodge conjecture is known in certain special cases, e.g., when the solution set has dimension less than four. But in dimension four it is unknown.
