metahamiltonian groups and related topics
a group $g$ is called metahamiltonian if all its non-abelian subgroups are normal. the aim of this paper is to provide an updated survey of research concerning certain classes of generalized metahamiltonian groups, in various contexts, and to prove some new results. some open problems are listed.
متن کاملRamifications and related topics
In some setting objects that are close to having the property may be almost as good for these settings as objects that have the property (e.g., see some of the settings discussed in Section [intro:benefits]). But in such a case, when testing for the property, it may be desirable not to reject objects that are very close to having the property (or, put differently, “tolerate” a small deviation)....
متن کاملMaximally nonlocal theories cannot be maximally random.
Correlations that violate a Bell inequality are said to be nonlocal; i.e., they do not admit a local and deterministic explanation. Great effort has been devoted to study how the amount of nonlocality (as measured by a Bell inequality violation) serves to quantify the amount of randomness present in observed correlations. In this work we reverse this research program and ask what do the randomn...
متن کاملPerfect codes and related topics
The topic of perfect codes is one of the most important topics in the theory of error-correcting codes. The class of perfect codes is very complicated, large (double exponential) and intensively studied by many researches. The investigation of nontrivial properties of perfect codes is significant both from coding point of view (for the solution of the classification problem for such codes) and ...
متن کاملInterval graphs and related topics
Interval graphs have engaged the interest of researchers for over twenty-five years. The scope of current research in this area now extends to the mathematical and algorithmic properties of interval graphs, their generalizations, and graph parameters motivated by them. One main reason for this increasing interest is that many real-world applications involve solving problems on graphs which are ...
