Abstract

Let f:ABf: A\rightarrow B be a ring homomorphism and let JJ be an ideal of BB. The purpose of this article is to examine the transfer of the properties of nn-coherence and strong nn-coherence from a ring AA to his amalgamated algebra AfJA\bowtie^{f} J. Also, we investigate the (n,d)(n,d)-property of the amalgamated algebra AfJA \bowtie^{f}J, to resolve Costa's first conjecture.
