21. The general setting for the study of differential forms is on a differentiable manifold. 22. Differential forms can be moved from one manifold to another using a smooth map.23. Differential forms arise in some important physical contexts.24. The Divergence Theorem allows Gauss's Law to be written in differential form : 25. Sections of the exterior bundle are differential forms on " M ". 26. In the language of differential forms and exterior derivatives, the gradient theorem states that 27. It has important consequences for the theory of differential forms , whose applications include electrodynamics. 28. Geometric calculus extends the formalism to include differentiation and integration including differential geometry and differential forms . 29. These, though, are usually described using the differential form of this equation given below. 30. Differential-forms,-forms, and-forms are special cases of differential forms .
