Abstract: We establish a vanishing result for the $L_{q,p}$-cohomology (${q\ge p}$) of a twisted cylinder, which is a generalization of a warped cylinder. The result is new even for warped cylinders. We base on the methods for proving the $(p,q)$-Sobolev–Poincaré inequality developed by L. Shartser.

Keywords: differential form, Sobolev–Poincaré inequality, $L_{q,p}$-cohomology, twisted cylinder, homotopy operator.
