例句與造句
- The entropy attains an extremum when the functional derivative is equal to zero:
- The extrema of functionals may be obtained by finding functions where the functional derivative is equal to zero.
- Observe that this expression vanishes implies the functional derivative vanishes, giving us the Wheeler-DeWitt equation.
- Thus one might want a derivative with some of the features of a functional derivative and the covariant derivative.
- It states : " In mathematics and theoretical physics, the functional derivative is a generalization of the gradient.
- It's difficult to find functional derivative in a sentence. 用functional derivative造句挺難的
- A similar statement may be made for the Diffeomorphism constraint ( take functional derivative with respect to the shift functions instead ).
- In functional analysis, the functional derivative defines the derivative with respect to a function of a functional on a space of functions.
- Because of this, the effective action is only defined over these special backgrounds and the functional derivative is not well-defined.
- I just read the article about functional derivatives, and while I think I understand the idea now, I am confused about the introduction.
- For other functional forms, the definition of the functional derivative can be used as the starting point for its determination . ( See the example Coulomb potential energy functional .)
- Expanding in " g " and computing the functional derivatives, we are able to obtain all the " n "-point functions with perturbation theory.
