We consider Einstein-like gravitational equations with Lambda term proporti
onal to the trace of the energy tensor. The possibility of Lagrangian formu
lation is shortly discussed. The theory is consistent with the present-day
observations, both at the local and cosmological level. Horizon-free cosmol
ogical solutions are found and discussed. The initial condition S(0) = 0 (w
here S(t) is the expansion factor and t the cosmic time) requires hyperboli
c space.
