Exact solitary and periodic-wave solutions of the K(2,2) equation (defocusing branch) [PDF]
An auxiliary elliptic equation method is presented for constructing exact solitary and periodic travelling-wave solutions of the K(2, 2) equation (defocusing branch). Some known results in the literature are recovered more efficiently, and some new exact

Cosmological Solutions of Integrable F(R) Gravity Models with an Additional Scalar Field
We consider F(R) cosmological models with a scalar field. For the R2 model in the spatially flat Friedmann–Lemaître–Robertson–Walker metric, the Ricci scalar R can smoothly change its sign during the evolution if and only if the scalar field is a phantom

EXACT INFLATIONARY SOLUTIONS [PDF]
We present a new class of exact inflationary solutions for the evolution of a universe with spatial curvature, filled with a perfect fluid, a scalar field with potential V±(ϕ) = λ(ϕ2 ± δ2)2 and a cosmological constant Λ. With the V+(ϕ) potential and a negative cosmological constant, the scale factor experiments a graceful exit.

Comments on the exact solutions of Mathieu's equation by D. J. Daniel (2020) [PDF]
So-called exact solutions of Mathieu’s equation proposed by D. J. Daniel [Prog. Theor. Exp. Phys. 2020, 043A01 (2020)] are flawed and not computable.
