A simple proof of a theorem on quasi-Baer rings.
The author presents a simple proof of a theorem by \textit{G. F. Birkenmeier, J. Y. Kim} and \textit{J. K. Park} [J. Pure Appl. Algebra 159, No. 1, 25-42 (2001; Zbl 0987.16018)], which states that if \(R[x,x^{-1}]\) or \(R[\![x,x^{-1}]\!]\) is quasi-Baer, then so is \(R\).
