Correspondence of F(R) gravity singularities in Jordan and Einstein frames might be non-singular in the other frame. In the unimodular F(R) gravity case, the unimodular

Compositional workflow modeling with priority constraints propose a
constraint-based approach to formalize priority in Reo. We introduce special channels
Determination of constraint stabilization parameters with multiple roots of characteristic equation to this method first time derivatives of
constraint equations are not considered as first integrals
Modeling of dynamics processes and dynamics control in deviations from the
constraint equations in the numerical solution. Common methods of
