WebFeb 28, 2013 · Modern differential geometry focuses on "geometric structures" on such manifolds, such as bundles and connections; for questions not concerning such structures, use (differential-topology) instead. Use (symplectic-geometry), (riemannian-geometry), (complex-geometry), or (lie-groups) when more appropriate.

The only prerequisites are multivariate calculus and linear algebra; no knowledge of topology is assumed. The powerful and concise calculus of differential forms is used throughout.

Web2 Differential 2-forms Any function ψ: D× Rm × Rm → R satisfying the above two conditions will be called a differential 2-form on a set D⊆ Rm. By contrast, differential forms of LI will be called from now on differential 1-forms. 3 Exterior product Given two differential 1-forms ϕ 1 and ϕ 2 on D, the formula ψ(x;v 1,v 2)˜det ϕ 1(x;v ... WebDec 27, 2024 · We have no norm of a differential form, and without norm we cannot define variations as Frechet derivatives. Moreover! We cannot even define a local extremum of a functional. Can you tell me how is defined variation of such functional, and a differential form? Does it even make sence what physicists are doing? differential-geometry …
