We investigate how the comoving curvature and tensor perturbations are transformed under generalized disformal transformation with second-order covariant derivatives of scalar field, where free functions depend on fundamental elements constructed field at most quadratic order derivatives. Our analysis reveals that superhorizon scales difference between in original new frames is given by combina...

This paper deals with mainly establishing numerous sets of generalized second-order parametric sufficient optimality conditions for a semiinfinite discrete minmax fractional programming problem, while the results on semiinfinite discrete minmax fractional programming problem are achieved based on some partitioning schemes under various types of generalized second-order (F ,β, φ, ρ, θ, m)-univex...
