Authors’ summary: “We study the derivation Lie algebra of the higher rank Virasoro-like algebra. We prove that it is isomorphic to the skew derivation Lie algebra. We also characterize the automorphism groups of the higher rank Virasoro-like algebra and the skew derivation Lie algebra. This generalizes the result of some related references.”
The main results are, however, special cases resp. easy consequences of two papers of K. Zhao and D. Ž. Đoković [J. Algebra 193, No. 1, 144–179 (1997; Zbl 0978.17015) and J. Pure Appl. Algebra 127, No. 2, 153–165 (1998; Zbl 0929.17025)].
