abstract:
We apply the basic concepts of vector optimization theory to certain problems 
arising in the asymptotic theory of total differential equations. This approach 
enables us to establish  interrelations between characteristic functionals 
and characteristic exponents, which are the main asymptotic characteristics of 
solutions of these equations. We are also enabled to construct a set of proper 
characteristic functionals with a number of useful properties. Using these 
results, we study the structure of characteristic sets, the properties of weakly 
regular linear total differential equations, and the behavior of characteristic 
functionals of equations under exponentially decreasing perturbations.
