The presented numerical method acquires a second-order convergence in discrete maximum norm. The derived results are numerically validated in test problems to support the theoretical analysis. 2010 Mathematics Subject Classification: 45D05; 45J05; 65L20; 65L70; 65R20en10.18514/MMN.2024.4562info:eu-repo/semantics/openAccessVolterra delay integro-differential equationfinite differenceuniform convergenceerror estimateArticle2522-s2.0-85212308530WOS:001402251100002Q2Q2
