Oceanic Types and Their Controls,e variation of parameters on which the object being studied depends. The objects can be diverse: for example, real or complex curves or surfaces, functions or mappings, manifolds or fiber bundles, vector fields or equations, differential or integral.

This is possible because, physically speaking, non-interacting particles can be described by either the partial differential equation of the field or ordinary equations for the particles.

Significance to Ecosystem Management,l collection of methods for the study of equations close to equations of a specific form. These equations are called ., and their solutions are assumed to be known. Perturbation theory studies the effect of small changes in the differential equations on the behavior of solutions.

The Humid Temperate Ecoregions,A fruitful technique for many differential equations consists of transforming (but not solving) them to a simpler form. Poincaré’s theory of normal forms produces such simple forms to which a differential equation can be reduced in the neighborhood of an equilibrium position or a periodic motion.
