70: Mechanics of particles and systems


Mechanics of particles and systems: studies dynamics of sets of particles or solid bodies, including rotating and vibrating bodies. Uses variational principles (energy-minimization) as well as differential equations.

Note that mathematically speaking, classical problems in celestial mechanics belong in this section, since bodies in space are treated as (very big!) particles.



Applications and related fields

For relativistic mechanics, See 83-XX 83A05 and 83C10; for statistical mechanics, See 82-XX

Clearly the study of the dynamics of smoothly moving systems requires the use of (systems of) differential equations.

Among the other branches of mathematics useful for these investigations, we mention geometric topology, which can provide a language for describing sets of movements, and commutative algebra, which can allow algebraic calculations of constraints on complex moving systems.

Some comments should be made about mathematical physics and engineering (subject headings 70-86) generally, but they don't easily fit the areas of the MSC. For now, they'll go here. For example, one should note that "field theory" used in these sections has nothing to do with "field theory" in abstract algebra. [Schematic of subareas and related areas]


Until the late 1970s the AMS used a major heading 69, General Applied Mathematics. Many of the reviews in that area could arguably be reclassed now into heading 70, Mechanics.
