for f, g being PartFunc of REAL,REAL st dom f = right_closed_halfline 0 & dom g = right_closed_halfline 0 & ( for s being Real st s in right_open_halfline 0 holds
f (#) (exp*- s) is_+infty_ext_Riemann_integrable_on 0 ) & ( for s being Real st s in right_open_halfline 0 holds
g (#) (exp*- s) is_+infty_ext_Riemann_integrable_on 0 ) holds
( ( for s being Real st s in right_open_halfline 0 holds
(f + g) (#) (exp*- s) is_+infty_ext_Riemann_integrable_on 0 ) & One-sided_Laplace_transform (f + g) = (One-sided_Laplace_transform f) + (One-sided_Laplace_transform g) )
