We describe a general framework for covering concepts using terminologies and briefly present the already investigated instances of this framework. Then, we formalize the best covering problem in the context of the ALN language, in which the difference operation is not semantically unique, and sketches the technique to solve the underlying computation problems.

In the paper we prove a factorization theorem for representations of fundamental groups of compact Kähler manifolds (Kähler groups) into solvable matrix groups. We apply this result to prove that the universal covering of a compact Kähler manifold with a residually solvable fundamental group is holomorphically convex.

<p><span>This paper aimed to study how reduce the amounts of heat transfer from or internal space building by covering its external walls with many locally available materials, thus reducing rate consumption electrical energy used in adaptation, which leads costs. The researcher built a model room dimensions (1 x 1 2) m on third floor Baghdad (L = 33.2 N), 2 m) east for installation...

in this paper, we develop a capacitated location-covering model considering interval values for demand and service parameters. we also consider flexibility on distance standard for covering demand nodes by the servers. we use the satisfaction degree to represent the constraint of service capacity. the proposed model belongs to the class of mixed integer programming models. our model can be redu...
