Abstract :Let $\\mathbb{A}=\\mathbb{R}_{+}\\times \\mathbb{R}$ be the affine group with a right Haar measure $\\mu$, $\\omega$ be a weight function on $\\mathbb{A}$ and $\\Phi$ be a Young function. We characterize the affine continuous mappings on the subsets of $L^\\Phi(\\mathbb{A},\\omega)$. Moreover we show that there exists an isometric isomorphism between the multiplier for the pair $(L^{1}(\\mathbb{A})\\cap L^{\\Phi}(\\mathbb{A}),L^{1}(\\mathbb{A}))$ and the space of bounded measures $M(\\mathbb{A})$.
