A photo of Samuel T. Walker, son of Elkanah Walker and Mary Richardson Walker, and his wife, Lucy Edith (Mckune) Walker. They are posed with the side-saddle Mary rode on the trip west.[front] The side-saddle Mary Walker rode on the trip west in 1838 -- now in O.H.S. in Portland (S. T. Walker + wife). [back] Sam Walker, Lucy Walker. In the foreground the side saddle Mary R. Walker rode crossing the country in 1838. Now in Oregon Hist. Society

f(R,T)=f(R)+λT gravity models as alternatives to cosmic acceleration
Abstract This article presents cosmological models that arise in a subclass of f(R,T)=f(R)+f(T) gravity models, with different f(R) functions and fixed T-dependence. That is, the gravitational lagrangian is considered as f(R,T)=f(R)+λT , with constant λ . Here R and T represent the Ricci scalar and trace of the stress-energy tensor, respectively. The modified gravitational field equations are obtained through the metric formalism for the Friedmann–Lemaître–Robertson–Walker metric with signature (+,-,-,-) . We work with f(R)=R+αR2-μ4R , f(R)=R+kln(γR) and f(R)=R+me[-nR] , with α,μ,k,γ,m and n all free parameters, which lead to three different cosmological models for our Universe. For the choice of λ=0 , this reduces to widely discussed f(R) gravity models. This manuscript clearly describes the effects of adding the trace of the energy-momentum tensor in the f(R) lagrangian. The exact solution of the modified field equations are obtained under the hybrid expansion law. Also we present the Om diagnostic analysis for the discussed models
