Slant and Legendre null curves in 3-dimensional Sasaki-like almost contact B-metric manifolds

Object of study in the present paper are slant and Legendre null curves 3-dimensional Sasaki-like almost contact B-metric manifolds. For examined we express general Frenet frame for which original parameter is distinguished, as well corresponding curvatures, terms structure on manifold. We prove that curvatures a framed curve constants if only specific function considered manifolds constant. find necessary sufficient condition to be generalized helix cubic. some investigated show they non-null or with respect associated give examples curves. Some them constructed Lie group manifold their matrix representation obtained.
