By using a derivative, you can take a supply function and determine the marginal revenue at any given quantity of product.

Coefficient bounds for functions with a positive real part are used in a rather novel way to find sharp bounds for the first six coefficients of a function which is inverse to a regular normalized ...

Exponential dichotomies can be used in discretized PDEs and in lattice differential equations to construct multi-pulses, to perform Evans-function type calculations, and to justify numerical ...
