On Generalizations of PF-Rings

Communications in Algebra, 2004
Abstract A ring R is called a right WPF-ring (weak PF-ring) if R is a semiperfect right simple-injective ring with essential right socle. The class of right WPF-rings is broader than that of right PF-rings. In this article, we study and provide several characterizations of this new class of rings.

A NEW CLASS OF PF-RINGS

JP Journal of Algebra, Number Theory and Applications, 2017
Summary: Let \(R\) be a commutative ring and \(S\) be the monoid generated by \(\{u\}\) with 0 added, with the relation \(u^n=0\), where \(n\geq2\) is a natural number. In this paper, we show that if \(R\) is a PF-ring in the sense that every finitely generated projective \(R\)-module is free, then the monoid ring \(R[S]\) is also a PF-ring.

Upgrade of the PF Ring Vacuum Control System

Proceedings of the 2005 Particle Accelerator Conference, 2006
Vacuum control system of the KEK Photon Factory (PF) storage ring has been upgraded in the summer of 2004 for the first time since the PF ring operation started in 1982. The new vacuum control system is based on PLC (Programmable Logic Controller) and EPICS (Experimental Physics and Industrial Control System)[1].
