A universal source of difficulty in the numerical solution of differential equations is stiffness, which may stem from multi-scale dynamics and means that straightforward explicit discretizations are very inefficient. Consequently, choosing how to deal with stiffness (usually through the selection of the time discretization method) is often the most impactful decision made while solving these problems; it can be the difference between complete intractability and rapid solution. The aim of this workshop is to advance the field of time evolution for PDEs by bringing together a broad community that will address this important issue in a variety of ways.

Dear Colleague We cordially invite you to join the 21st International Geometry Symposium co-organized by the Society of Geometers and Erzurum Technical University. The symposium will be a hybrid event – hosted online simultaneously with a face-to-face event – at the Erzurum Technical University, Erzurum, Turkey, on July 17-19, 2025. The main aims of this symposium are to carry out and share studies for the development, understanding, and dissemination of geometry. Since established in 2003, the annual Geometry Symposiums have been devoted to highlighting and sharing the latest developments in geometry and its applications.We expecy your valuable scientists to contribute and participate together with your work that will open new horizons in the field of geometry.Hope to see you at the symposium. We would be delighted to welcome you to Erzurum Technical University in Erzurum. We are looking forward to seeing you at the 21st International Geometry Symposium. Best Regards, Assoc.Prof.Dr Sibel TURANLI Chariman of the Organizing Committee

The 36th International Workshop on Operator Theory and its Applications (IWOTA) will bring together leading international experts for an exchange of ideas, results and methods, and for tracing the future development in operator theory, complex analysis, harmonic analysis, linear algebra, random matrix theory, mathematical physics, and their applications ranging from deep learning to control theory.

The conference continues a series of ring theory conferences in Graz from 2012, -14, -16, -18, -21, and 2023. The focus lies on algebraic, number theoretic and topological aspects of rings, algebras and polynomials, including: Integer-valued polynomials Polynomial mappings Multiplicative ideal theory Topological methods in ring theory Zariski-Riemann spaces of valuation domains Factorization theory in rings and monoids Module theory and linear algebra over rings Dedekind, Prüfer, and Krull domains and generalizations.

MIMAR is the premier maintenance and reliability modelling conference. It is an excellent international forum for disseminating information on the state-of-the-art research, theories and practices in maintenance and reliability modelling and offers a platform for connecting researchers and practitioners from around the world.

This will be a one-week conference broadly focused on the topics of the L-functions and Modular Forms Database (http://lmfdb.org), mathematical databases, computation, and number theory. The conference will include invited talks, presentations by authors of papers submitted to the conference and selected by the scientific committee following peer-review, as well as time for research and collaboration. We plan to publish a proceedings volume that will include all of the accepted papers.

The symposium will cover, but not limited, various topics in differential geometry; including Riemannian and sub-Riemannian geometry, geometric structures on manifolds, Finsler and contact geometry, information geometry, and their applications in mathematical physics, relativity theory, and data science.
