The boundary between mathematics and physics has often been a source of tension. This tension frequently revolves around a central notion: mathematical rigour. Although the concept has been discussed in history\, philosophy\, and mathematics itself\, there has been relatively little discussion of its relationship to physics. Physics is often considered unrigorous\; however\, given that there is no single agreed-upon notion of rigour even within mathematics\, it becomes unclear exactly why physics is regarded as unrigorous\, and whether it should be.
\n\; This interdisciplinary workshop will bring together researchers from various fields to discuss both descriptive and normative notions of rigour in physics\, as well as the influence of this topic on the concept of rigour in mathematics. The central\, but non-exhaustive questions of the workshop will include the following:

The Conference (including also \;special streams and sessions) discusses all aspects of numerical computations and modeling from foundations and philosophy to advanced numerical techniques. New technological challenges and fundamental ideas from theoretical computer science\, linguistic\, logic\, set theory\, and philosophy meet requirements and new fresh applications from physics\, chemistry\, biology\, and economy.
\nAmong approved special streams:
\n- \;Philosophy of applied mathematics
\n- \;Frontiers in mathematics and STEM education: From formal methods to AI-driven computational tools

\nSpecial Issue on the Principle of Identity of Indiscernibles
\nManuscrito: International Journal of Philosophy invites submissions in English for a special issue devoted to the Principle of Identity of Indiscernibles (PII).
\nGuest Editor: Leonardo G. S. Videira (University of Sã\;o Paulo &ndash\; FAPESP)
\nThe Principle of Identity of Indiscernibles (PII)\, in its most widespread formulation\, states that any two things sharing all the same properties are in fact identical\; in other words\, no two distinct things share all their properties. Despite its apparent simplicity\, the principle has remained one of the most contested theses in the history of metaphysics. Classical and contemporary counterexamples &ndash\; such as Kant&rsquo\;s droplets\, Black&rsquo\;s spheres\, and entangled bosons &ndash\; appear to involve numerically distinct yet indiscernible entities\, thereby challenging the principle's truth.
\nDebates concerning the PII extend well beyond the question of its truth or falsity\, however. They encompass issues regarding the interpretation of its constituent notions\, the modal status of the principle\, and the nature of the necessity\, if any\, that underwrites it. Moreover\, the PII plays a central role in a wide range of philosophical discussions\, including the dispute between bundle and substratum theories\, the ontology of quantum mechanics\, the metaphysics of mathematical objects\, and the relationship between indiscernibility and identity.
\nThe last two decades have witnessed significant developments in these debates. This special issue aims to bring together contributions that advance our understanding of the PII\, its implications\, and its applications across different areas of philosophy.

\n&lsquo\;(Perceived) Dichotomies in Mathematics: Opposites\, Boundaries\, and Tensions in the History and Philosophy of Mathematics&rsquo\;
\n&mdash\; Call for Abstracts &mdash\;
\nhttps://novembertagung.wordpress.com/novembertagung-2026/ \;
\nThe Novembertagung on the History and Philosophy of Mathematics is an international conference aimed at PhD students and early-career researchers in the history\, philosophy of mathematics and related areas. This event offers an opportunity to share your work in progress in a collegial atmosphere and receive feedback.
\nThe 36th edition of the Novembertagung will take place in Istanbul (Turkey) from November 3rd to 5th\, 2026. It will be hosted by theInstitute for the History of Science at Istanbul Medeniyet University. The keynote speakers will be confirmed in the coming weeks. Please see the website for the most up-to-date information.
\nThe conference is planned as an in-person event. For those who require financial assistance\, please indicate so in your application as we may be able to provide some funding.
\nThis year&rsquo\;s Novembertagung theme centres on Opposites\, Boundaries and Tensions in the History and Philosophy of Mathematics. We will explore the ways in which mathematical belief\, disagreement and conflict are both formed and conducted\, and the ways that these tensions and disagreements shape both the content and perception of mathematical belief. Believing that mathematical disagreement is much more substantial than a question of &lsquo\;right&rsquo\; and &lsquo\;wrong&rsquo\;\, we call for papers that explore how Opposites\, Boundaries and Tensions are formed\, expressed and entrenched throughout mathematical history.
\nAbstracts about the following\, non exhaustive\, list of topics will be welcomed:
\nAbstract dichotomies: objects and concepts\, theory and practice\, informal and formal reasoning\, etc.
\nThe formation of mathematical disciplines
\nThe resolution of mathematical disputes
\nThe roles of institutions in forming mathematical culture
\nHistorical and Philosophical approaches to the treatment of mathematical disputation
\nHow mathematical and &lsquo\;extra-mathematical&rsquo\; thought interact in shaping mathematical and non-mathematical belief
\nHistoriographical work that explores how these concepts are treated in the literature. \;
\nWhile the topic of the submission should ideally be related to the conference&rsquo\;s theme\, most topics that fall under the broader heading of philosophy or history of mathematics\, and that can fruitfully be connected to it will be welcomed as valuable additions to the conference. Early-Career and graduate students working on conflict theory in academia and society more general\, or at the intersection of the History of Mathematics and science more generally for example\, are also welcome to submit their work.
\nPhD students and early-career researchers are invited to submit abstracts.
\nAbstracts should be written in English and not exceed 300 words.
\nAll submissions should be suitable for a 20-minute presentation\, followed by a 10-minute discussion.
\nAbstracts should be sent as a PDF file prepared for blind review (do not put your name nor affiliation in the abstract\, only in your email) to
\nnovembertagung.hpm@gmail.com \;
\nPlease include your full name and affiliation in your email.
\nWe expect to secure funding for accommodation expenses\, or travel in exceptional cases\, as mentioned earlier. Please\, let us know in your application if you would like to be considered for funding.
\nThe deadline for submissions is May 31st\, 2026.
\nIf you have any further questions\, feel free to contact the organisers atnovembertagung.hpm@gmail.com
