We characterize the exchange property for non-unital rings in terms of their local rings at elements,and we use this characterization to show that the exchange property is Morita invariant for idempotent rings.We also prove that every ring contains a greatest exchange idela(with respect to the inclusion).

The purpose of this note is to generalize a result of Gulliksen, Ribenboim and Viswanathan which characterized local group rings when both the ring and the group are commutative.We assume throughout that all rings are associative with identity. If R is a ring we call R local if R/J(R) is a division ring where J(R) denotes the Jacobson radical of R.

PSEUDOPOLAR MATRIX RINGS OVER LOCAL RINGS
Journal of Algebra and Its Applications, 2013A ring R is called pseudopolar if for every a ∈ R there exists p2 = p ∈ R such that p ∈ comm 2(a), a + p ∈ U(R) and akp ∈ J(R) for some positive integer k. Pseudopolar rings are closely related to strongly π-regular rings, uniquely strongly clean rings, semiregular rings and strongly π-rad clean rings.

Un anneau primitif localement compact non discret de caractéristique 0 est une algèbre de dimension finie sur son centre. Même conclusion pour un anneau simple localement compact et non discret possédant des idéaux minimaux. Un théorème de l'A. sur les anneaux semi-simples localement compacts bornés est géneralisé. Part II, voir Am. J. Math. 73, 20--24

On PM-rings, rings of finite character and h-local rings
Journal of Algebra and Its Applications, 2014In this paper, we investigate the transfer of the notions of pm-rings, rings of finite character and h-local rings to trivial ring extensions of rings by modules, amalgamations of rings along ideals and pullbacks. Our aim is to provide new classes of commutative rings satisfying these properties and our results generate new families of examples of ...
