CENTRALIZERS AND INDUCTION

Journal of Algebra and Its Applications, 2007
Given a ring homomorphism B → A, consider its centralizer R = AB, bimodule endomorphism ring S = EndBABand sub-tensor-square ring T = (A ⊗BA)B. Nonassociative tensoring by the cyclic modules RTorSR leads to an equivalence of categories inverse to the functors of induction of restricted A-modules or restricted coinduction of B-modules in case A | B is ...

Centralizers and Central Idempotents of Semigroup Rings

Semigroup Forum, 2001
A ring means an associative ring (not necessarily with unity). Let \(R\) be a ring, \(A\subseteq R\). The set \(C_R(A)=\{r\in R\mid ar=ra\) for all \(a\in A\}\) is called the centralizer of \(A\) in \(R\). Let \(S\) be a semigroup, and let \(R[S]\) be the semigroup ring of \(S\) over \(R\).

West and Central Africa

International Migration, 1998
In West and Central Africa, countries with high rates of emigration and immigration tend to have higher rates of HIV infection. However, there is one exception, Senegal, an exception demonstrating that high levels of mobility and migration do not necessarily lead to rapid and extensive spread of HIV infection.Five different population groups are ...

Central and Central-Eastern Malayo-Polynesian

Oceanic Linguistics, 1993
Malayo-Polynesian (CEMP). CEMP, encompassing all of the approximately 600 Austronesian languages of eastern Indonesia and the Pacific apart from Palauan, Chamorro, and possibly Yapese, is justified by a set of phonological, lexical, morphosyntactic, and semantic innovations that distinguish these languages from the reconstructed ancestor of the ...

Ergothioneine and Central Neurones

Nature, 1965
Crossland, Woodruff and Mitchell1 have recently identified the ‘cerebellar excitatory factor’2,3 as ergothioneine. This factor had been found in extracts of the cerebellum from several mammalian species3 and it was said to have a potent excitatory action on the electrical activity of the cerebellum and the cerebral cortex when injected into the carotid

Alcohol and central neurotransmission

Neurochemistry International, 1988
The study of the relationships between alcohol consumption and central neurotransmission is difficult: they are different from one individual to another, from one neurotransmission system to another and from one cerebral area to another. Moreover, there is no fully satisfactory animal model of alcoholism and the human studies have to cope with a lot of
