Surfaces on Helmholtz-Type Groups

  • V. A. Kyrov

摘要

We consider surfaces on the pseudo-Helmholtz, proper Helmholtz, and dual Helmholtz Lie groups.These groups are united under the common term: Helmholtz-type groups.The Dirac, Weingarten, and Codazzi equations in the spinor representation are derived.The energy functional on these groups is studied.
