    Coherence in amalgamated algebra along an ideal

    Full text link
    Let f:Aโ†’Bf: A\rightarrow B be a ring homomorphism and let JJ be an ideal of BB. In this paper, we investigate the transfert of the property of coherence to the amalgamation Aโ‹ˆfJA\bowtie^{f}J. We provide necessary and sufficient conditions for Aโ‹ˆfJA\bowtie^{f}J to be a coherent ring
