Аннотация
Questions relating to the search of geodesics in a series of left-invariant problems with sub-Lorentzian and Finsler structure are under consideration. Explicit formulae for extremals are found in terms of trigonometric functions of convex trigonometry. In sub-Lorentzian problems the machinery of the new trigonometric functions $\sinh_\Omega$ and $\cosh_\Omega$ , generalizing $\sinh$ and $\cosh$ to the case of an unbounded convex set $\Omega\subset\mathbb R^2$ , is particularly useful.
