The \(SQ\)-universality of one-relator products of cyclics
The question: ``Does \(SQ\)-universality hold for the one-relator product of cyclics \[ G = \langle a_ 1,\dots,a_ n \mid a_ 1^{e_ 1} = \dots = a_ n^{e_ n} = R^ m(a_ 1,\dots,a_ n) = 1\rangle, \] where \(n\geq 2\), \(m \geq 2\), \(e_ i = 0\) or \(e_ i \geq 2\) for \(i = 1,\dots,n\), \(R(a_ 1,\dots,a_ n)\) a cyclically reduced word in the free product on \(a_ 1,\dots,a_ n\) which involves \(a_ 1,\dots,a_ n\)?'' is investigated in this paper.
