Abstract


In the present paper, first we characterize the multiplier algebra, (maximal) ideals, minimal idempotents, spectrum and radical of the generalized amalgamated Banach algebra $A\boxtimes_\Theta X$ in terms of $A$ and $X$ and the bilinear mapping $\Theta$ from $X\times X$ into $A$. Then, we show that there are a strong relationship between some of homological properties of $A\boxtimes_\Theta X$, such as Connes-amenability, flatness and projectivity, $\phi$-biprojectivity, and the Banach algebras $A$ and $X$ and the mapping $\Theta$. The results of this paper extend several results in the literature.
