Separation of Concerns in OFL
OFL (Open Flexible Languages) is the name of a meta-model for object-oriented programming languages based on classes. It relies on three essential concepts of these languages: the descriptions which are a generalisation of the notion of class, the relationships such as inheritance or aggregation and the languages themselves. OFL provides a customisation (hyper-genericity) of these three concept...
متن کاملElementary classes of groups
For a given family of groups B, we define an elementary class E(B) as the smallest class of groups, that contains B and is closed under the passing to subgroups, quotients, and taking extensions and direct limits. The properties of these classes are considered. The proposed theory has close connections with the theory of elementary amenable groups as well as of Kuroš – Černikov classes.
متن کاملAn Lil Version Ofl =
This pqjer establi^es a law-of-the-iterated-logarithm (LIL) version of the fundamental queueing fonnula i — X(f: Under regularity conditions, the continuous-time arrival counting process and queue-length process jointly obey an LIL when the discrete-time sequence of interanival times and waiting times jointly obey an LIL, and the limit sets are related. The standard relation L — \W appears as a...
متن کاملThe graph of equivalence classes and Isoclinism of groups
Let $G$ be a non-abelian group and let $Gamma(G)$ be the non-commuting graph of $G$. In this paper we define an equivalence relation $sim$ on the set of $V(Gamma(G))=Gsetminus Z(G)$ by taking $xsim y$ if and only if $N(x)=N(y)$, where $ N(x)={uin G | x textrm{ and } u textrm{ are adjacent in }Gamma(G)}$ is the open neighborhood of $x$ in $Gamma(G)$. We introduce a new graph determined ...
متن کاملnew classes of infinite groups
in this article, we consider some new classes of groups, namely, mp-groups, t0-groups,ø-groups,ø0-groups, groups with finitely embedded involution, which were appeared at the end of twenties century. these classes of infinite groups with finiteness conditions were introduced by v.p. shunkov. we give some review of new results on these classes of groups.
