Abstract
We study finite-time future singularities in F(R,G)-gravity, where R and G are the Ricci scalar and the Gauss-Bonnet invariant, respectively. In particular, we reconstruct the F(G)-gravity and F(R,G)-gravity models realizing the finite-time future singularities.We discuss a possible way to cure the finite-time future singularities in F(R,G)-gravity by taking into account higher-order curvature corrections or effects of viscous fluids.
