idrissi.eu is the personal mathematics website of Najib Idrissi. According to the site, the author is an associate professor at Université Paris Cité, affiliated with the Institut de Mathématiques de Jussieu–Paris Rive Gauche, and serves as deputy project leader for the Algebraic Geometry & Topology team. This is not a commercial online education platform, but rather a personal academic repository bringing together papers, preprints, dissertations, course materials, seminar talks, and research notes.
From an education/course perspective, the main available resources include materials for the “Algèbre 2025–2026” course at Université Paris Cité, aimed at M1 Mathématiques-Informatique Cryptographie students. It lists 24 hours of lectures and 33 hours of tutorial sessions, with links to Notes, TD, corrections for continuous quizzes, and exam corrections. There is also a 6-hour lecture course titled “Introduction à la théorie des graphes.” The research focus is highly specialized, centered on advanced mathematical topics such as algebraic topology, configuration spaces, operads, and homotopy theory.
The site does not show course pricing, subscriptions, payment methods, or enrollment options. The visible links include PDFs, lecture notes, source code, arXiv, HAL, and similar academic resources, so it functions more like a free public academic resource. It also does not mention course completion certificates, academic credit, or online learning credentials.
Its main strengths are strong academic credibility and a clearly stated institutional background. The materials include formally published papers, Lecture Notes in Mathematics, HDR/PhD dissertations, and course handouts, making it suitable for serious study and research citation. The drawbacks are also clear: the site is not designed for general learners, and it lacks structured learning paths, video explanations, interactive Q&A, assignment grading, and learning assessment. The content has a very high technical barrier, making it difficult for non-math majors or beginners to use directly.
This site is best suited to master’s students, PhD students, and researchers in mathematics, especially those interested in configuration spaces, operads, homotopy, and algebraic topology. If you simply want to study basic algebra or graph theory, or are looking for a certifiable online course, this website is better used only as supplementary material.
The page does not provide information about access from mainland China, so it is not possible to determine whether the site can be reached directly. Since the site relies on external links such as PDFs, arXiv, HAL, and Springer, the actual browsing experience may vary depending on the network environment.
