Since one of the most promising approach for an exact solution of a hard combinatorial optimization problem is the cutting plane method, (see [9] or [13] for the symmetric TSP, [4]

In this work we give definitions of the notions of superior limit and inferior limit of a real distribution of n variables at a point of its domain and study some properties of

In this section we prove the lemmas used to obtain Theorem A and The Main Theorem in section 4.. Since all of the results of this section are stated for W(,z)

This problem becomes more interesting in the case of a fractional differential equation where it closely resembles a boundary value problem, in the sense that the initial value

It is well known that the Castelnuovo-Mumford regularity of a finitely gen- erated Z -graded module M can be defined either in terms of degree bounds for the generators of the

Let T (E) be the set of switches in E which are taken or touched by the jump line of E. In the example of Fig. This allows us to speak of chains and antichains of switches.. An

For example, it is not obvious at all that the invariants of rooted trees given by coefficients of the generating functions f (t ), ˜ d(t ), ˜ h(t ) ˜ and m(t ) can be obtained

Actually it can be seen that all the characterizations of A ≤ ∗ B listed in Theorem 2.1 have singular value analogies in the general case..
