On a property of ϕ-variational modular spaces
Abstract. Maligranda pointed out whether condition (B.1) is satisfied in the variational modular space \(X_{\rho}^{*}\) is an open problem. We will answer this open problem in \(X_{\rho}^{*\prime}\), a subspace of \(X_{\rho}^{*}\). As a consequence this modular space can \(X_{\rho}^{*\prime}\) be \(F\)-normed.
Keywords: condition (B.1), modular, \(\phi\) -function, \(\phi\) -variation.
