Abstract

We, the Editors and Publisher of International Journal of Computer Mathematics have retracted the following article: Sudhir Kumar, R.C. Mittal & Ram Jiwari (2023) A cubic B-spline quasi-interpolation method for solving hyperbolic partial differential equations, International Journal of Computer Mathematics, DOI: 10.1080/00207160.2023.2205963 Since publication, significant concerns have been raised about the fact that this article has substantial overlap with the following article which was not acknowledged, particularly in Sections 1-4 where there were verbatim sentences and sentence fragments: Mittal, R. C., Kumar, S., & Jiwari, R. (2021). A cubic B-spline quasi-interpolation algorithm to capture the pattern formation of coupled reaction-diffusion models. Engineering with Computers, 1-17 https://doi.org/10.1007/s00366-020-01278-3. Upon query, the authors were not able to address the concerns with their paper or provide a satisfactory explanation for this significant level of overlap. As this is a serious breach of our Editorial Policies, we are retracting the article from the journal. The authors do not agree with the retraction. We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.

求解双曲型偏微分方程的三次b样条拟插值方法

我们，国际计算机数学杂志的编辑和出版商已经撤回了以下文章:Sudhir Kumar, R.C. Mittal和Ram Jiwari(2023)求解双曲型偏微分方程的三次b样条拟插值方法，国际计算机数学杂志，DOI:10.1080/00207160.2023.2205963自发表以来，人们对这篇文章与以下文章有大量重叠的事实提出了重大关切，这篇文章没有得到承认，特别是在第1-4节中，有逐字句子和句子片段:Mittal, R. C.， Kumar, S.， & Jiwari, R.(2021)。一种三次b样条准插值算法捕捉耦合反应扩散模型的模式形成。计算机工程，1-17 https://doi.org/10.1007/s00366-020-01278-3。经询问，作者无法在他们的论文中解决这些问题，也无法对这种显著程度的重叠提供令人满意的解释。由于这严重违反了我们的编辑政策，我们将从杂志上撤回这篇文章。作者不同意撤稿。我们的出版道德和诚信政策以及COPE关于撤稿的指导方针已经通知了我们的决策。撤回的文章将保留在网上，以保持学术记录，但每页都会有数字水印标记为“撤回”。

期刊介绍： International Journal of Computer Mathematics (IJCM) is a world-leading journal serving the community of researchers in numerical analysis and scientific computing from academia to industry. IJCM publishes original research papers of high scientific value in fields of computational mathematics with profound applications to science and engineering. IJCM welcomes papers on the analysis and applications of innovative computational strategies as well as those with rigorous explorations of cutting-edge techniques and concerns in computational mathematics. Topics IJCM considers include: • Numerical solutions of systems of partial differential equations • Numerical solution of systems or of multi-dimensional partial differential equations • Theory and computations of nonlocal modelling and fractional partial differential equations • Novel multi-scale modelling and computational strategies • Parallel computations • Numerical optimization and controls • Imaging algorithms and vision configurations • Computational stochastic processes and inverse problems • Stochastic partial differential equations, Monte Carlo simulations and uncertainty quantification • Computational finance and applications • Highly vibrant and robust algorithms, and applications in modern industries, including but not limited to multi-physics, economics and biomedicine. Papers discussing only variations or combinations of existing methods without significant new computational properties or analysis are not of interest to IJCM. Please note that research in the development of computer systems and theory of computing are not suitable for submission to IJCM. Please instead consider International Journal of Computer Mathematics: Computer Systems Theory (IJCM: CST) for your manuscript. Please note that any papers submitted relating to these fields will be transferred to IJCM:CST. Please ensure you submit your paper to the correct journal to save time reviewing and processing your work. Papers developed from Conference Proceedings Please note that papers developed from conference proceedings or previously published work must contain at least 40% new material and significantly extend or improve upon earlier research in order to be considered for IJCM.
