... Differential Equations), a monthly scientific mathematical journal, founded in 1965 and published in Minsk. The journal publishes results of studies on differential, integro-differential, and integral equations as well as on finite difference equations. It is translated into English in the United States and published under the title Differential Equations.
- Adjoint Differential Equation by Great Soviet Encyclopedia
a concept of the theory of differential equations. The adjoint of the differential equationis the differential equationThe relation is symmetric: L. ( y. ) = 0 is also the adjoint of M. ( z. ) = 0.Adjoint differential equations satisfy the identityThe expression ψ( y, z ) is known as the bilinear concomitant. It is linear in y...
- Chaplygin Inequality by Great Soviet Encyclopedia
one of the most important differential inequalities. Suppose y. ′( x. ) = f. ( x, y ) and the functions u. ( x. ) and v. ( x. ) satisfy the differential inequalities u. ′( x. ) – f. ( x, u ) > 0 v. ′( x. ) – f. ( x, v ) < 0where x. 0 ≤ x. ≤ x. 1. If u. ( x. 0) = v. ( x. 0) = y. 0, then the solution y. ( x. ) of the differential equation y. ′( x...

... the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is ...
