A new concept is proposed for linking algebraic modeling languages and the structure exploiting solver.

I will sketch the history of the so-called turnpike theorems and describe some interesting recent developments regarding them. I will also discuss the attempt to apply the ideas of turnpike theorems in the literature of optimal capital accumulation to the theory of competitive equilibrium over...

We present a new result on the asymptotic behavior of non-autonomous subgradient evolution equations.

In this paper we give an overview of the mostimportant characteristics of advanced implementations of interior point methods.

Galois connections (or residuated mapping) are of growing interest in various domains related with or relevant from Classification. Among their many uses, we select some topics related with modelization and aggregation of dissimilarities and conceptual classification. We partially revist them in...

In this paper we present several "infeasible-start" path-following and potential-reduction primal-dual interior-point methods for non-linear conic problems. These methods try to find a recession direction of the feasible set of a self-dual homogeneous primal-dual problem.

This paper adapts to the case of impulse and hybrid control systems the results obtained bu Aubin, Bicchi and Pancanti on "detectability" of solutions of usual control systems.

A generalization of the Roy-Gallai Theorem on the chromatic number of a graph is derived which is also an extension of several other results of Berge and of Li.
