Approximations to the non-interacting kinetic energy Ts[ρ], which take the form of semilocal analytic expressions are collected. They are grouped according to the quantities on which they explicitly depend. Additionally, the approximations for quantities related to Ts[ρ] (kinetic potential and non-additive kinetic energy), for which the analytic expressions for the "parent" approximation for the functional Ts[ρ] are unknown, are also given.
