These entities come in ordinary, linear, and partial types, among others.
Smoluchowski names an example of the stochastic type of these, another example of which are named for Langevin. Picard and Lindelöf name a theorem giving conditions under which these things are solvable. The shallow water and di usion ones are examples of these used in physics, and these things are called   homogenous if any linear combination of some of their solutions is another solution. Maxwell names a set of these which feature prominently in electrodynamics. These entities come in ordinary, linear, and partial types, among others. For ten points, identify this kind of equation which relates a function to one or more of its derivatives.
