GREEN'S RELATIONS AND MINIMAL QUASI-IDEALS IN RINGS
Communications in Algebra, 2002ABSTRACT In this paper we study the Green's relations , , , , as well as the relations concerning principal quasi-ideals in rings, whose definitions mimic definitions of Green's relations and relation in semigroups. We show that, differently from semigroups in rings we have in general , and we provide a sufficient, but not necessary, condition for , to

Small amplitude oscillations of a quasi-ideal pendulum
American Journal of Physics, 1979A variational principle, resembling that used in quantum mechanics, is formulated and applied to study the first-order correction to the period of a simple pendulum. The relevant small parameter is the ratio of the mass of the suspension cord to that of the pendulum bob.

Principal quasi-ideals of cohomological dimension 1.
2019The principal quasi-ideal generated by an element \(w\) of the semigroup \(S\) is the set \(\langle w\rangle_q=S^1w\cap wS^1\). The cohomological dimension of the semigroup \(S\) is the smallest integer \(n\) such that for any \(S\)-module \(A\) and \(k>n\) the \(k\)-th cohomology group \(H^k(S,A)\) is trivial.
