'Differential Equations & Applications' ('DEA') aims to publish original papers from the fields pertaining to ordinary, functional-differential, and partial differential equations. An equation denotes the relation between two quantity or two functions or two variables or set of variables or between two functions. C'est un cas particulier d'équation fonctionnelle.

…the application of analysis are differential equations, which relate the rates of change of various quantities to their current values, making it possible—in principle and often in practice—to predict future behaviour. /Length 174 /BBox [0 0 595.2 297.6] In terms of mathematics, we say that the differential equation is the relationship that involves the derivative of a function or a dependent variable with respect to an independent variable.
