D-system, limit-bounded system

A system of ordinary differential equations

with continuous right-hand side, whose solutions satisfy the properties of uniqueness and infinite extendability to the right, and for which there exists a number such that for any solution it is possible to find a moment in time such that

In other words, each solution is immersed, sooner or later, in a fixed sphere . An important particular case of a dissipative system are the so-called systems with convergence, for which all solutions are defined for and, in addition, there exists a unique bounded solution on the entire axis which is asymptotically stable in the large. Such systems have been thoroughly studied (see, for example, [1]).
