On the cutoff parameter in the translation-invariant theory of the   strong coupling polaron. (response to comments [arXiv:1204.4142] on the paper   V. D. Lakhno, SSC, 152, (2012), 621)
  The paper is a reply to the arguments adduced by the authors of Ref. [arXiv:1204.4142] against the results obtained by the author in Refs. [6,7]. It is shown that these arguments are based on the erroneous approach made in Ref. [arXiv:1204.4142] to the strong coupling limit when the cutoff parameter is introduced in the theory.
