Symmetric Bases and ${\ell }^p$ Embeddings in Musielak--Orlicz Sequence Spaces under ${\delta }_2$

Valentin Georgiev, Boyan Zlatanov

We study isomorphic embeddings into Musielak-Orlicz sequence spaces \(\ell_Φ\), where the normalized generating sequence \(Φ=\{ϕ_n\}\) satisfies the \(δ_2\) condition. Using admiss…
