Pointwise multipliers of Musielak–Orlicz spaces and factorization [PDF]

open access: yesRevista Matematica Complutense, 2020
AbstractWe prove that the space of pointwise multipliers between two distinct Musielak–Orlicz spaces is another Musielak–Orlicz space and the function defining it is given by an appropriately generalized Legendre transform. In particular, we obtain characterization of pointwise multipliers between Nakano spaces.

Pointwise multipliers of Orlicz spaces

open access: yesArchiv Der Mathematik, 2010
Let \((\Omega,\Sigma,\mu)\) be a complete \(\sigma\)-finite measure space and let \(L^0(\Omega)\) denote the class of measurable functions on \(\Omega\). If \((X,\|\cdot\|_X)\), \((Y,\|\cdot\|_Y)\) are Banach spaces of functions in \(L^0(\Omega)\), then \(M(X,Y)\), the space of pointwise multipliers, is defined by \[ M(X,Y)= \{y\in L^0(W): xy\in Y\text{
