new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

the effect of lexical inferencing and concept mapping on the vocabulary retention among iranian intermediate efl learners

this study was an attempt to investigate and compare the effect of lexical inferencing and concept mapping on developing vocabulary retention of iranian language learners. sixty homogeneous students from different intact classes who were being taught as intermediate learners in sokhan english institute participated in this study. they were in different classes. a teacher made test as a pre-test...

Mapping Tori of Endomorphisms of Free Groups

For a large class of endomorphisms of finitely generated free groups we prove that their mapping tori groups are word-hyperbolic if and only if they don’t contain Baumslag-Solitar subgroups.
