Comment on 'Lost in translation: topological singularities in group field theory'

Gurau argued in (Gurau R 2010 Class. Quantum Grav. 27 235023) that the gluing spaces arising as Feynman diagrams of three-dimensional group field theory are not all pseudo-manifolds. I dispute this conclusion: albeit not properly triangulated, these spaces are genuine pseudo-manifolds, namely their singular locus is of codimension at least 2. (comment)
