Proof theory for minimal quantum logic: A remark
This paper shows proof-theoretically that in the reviewer's [ibid. 33, 103-113 and 1427-1443 (1994; Zbl 0798.03062 and Zbl 0809.05045)] cut-free sequential system for minimal quantum logic the inference rule \[ {\Gamma\to \Delta\over \Delta'\to \Gamma'}\quad (\;'\to\;') \] is redundant.
