Approximation by Riemann sums in modular spaces

Hokkaido Mathematical Journal, 2001
Let \(Q=[ 0,1] \) and let \(L^{0}( Q) \) be the space of all Lebesgue measurable functions \(f:Q\to\mathbb{R}.\) A functional \(\rho:L^{0}( Q) \to[ 0,\infty] \) which satisfies the conditions: (i) \(\rho( f) =0\Longleftrightarrow f=0\) a.e. in \(Q\); (ii) \(\rho( -f) =\rho( f) \), for every \(f\in L^{0}( Q) \) and (iii) \(\rho( \alpha f+\beta g) \leq ...
