Held under the patronage of the Bernoulli Society, a major international scientific meeting on the theory and applications of stochastic processes.

The International Conference on Formal Power Series and Algebraic Combinatorics (FPSAC) is an interdisciplinary conference series, focusing on recent advances in algebraic and enumerative combinatorics as well as applications and relations to other areas of mathematics, physics, biology and bioinformatics, and computer science. As the most important algebraic and enumerative combinatorics conference in the world, FPSAC's one-week annual meeting brings together researchers in the international algebraic combinatorics community as well as other areas of combinatorics and theoretical computer science, and links them with leading scientists from allied disciplines in pure and applied mathematics, bioinformatics and physics.

ICoMS 2023 is organized to bring together researchers and practitioners interested in advancing the state of the art in Mathematics and Statistics, and for exchanging knowledge that encompasses a broad range of disciplines among various distinct communities. The themes for this conference are focused on "Mathematics of Digital Twins - Analysis, Stochastics and Numerics".

The workshop will be divided into the different aspects of mathematical modelling and its role on sciences. The three fundamental stones are: - Dynamical Systems (Integrable systems, Hamiltonian systems, new results for qualitative aspects of dynamical systems, celestial mechanics and the many-body problem, ergodic theory ...) - Control Theory (Geometric control, stabilization of control systems, optimal control, safety conditions, mathematical analysis of control systems, quantum control, distributed control, robotics applications, ...) - Geometric Mechanics (Geometric Integration, Reduction by symmetries, nonholonomic systems, stochastic mechanics, fluid dynamics, applications in material sciences and continuum mechanics; symplectic, cosymplectic and contact geometry ...)

The conference aims to bring together leading experts and researchers in fixed point theory and to assess new developments, ideas, and methods in this important and dynamic field. A special emphasis will be put on applications in related areas and other sciences, such as the natural sciences, medicine, economics, and engineering. The conference will continue the tradition of the previous fixed point theory meetings, which were held in Marseille (1989), Halifax (1991), Seville (1995), Kazimierz Dolny (1997), Haifa (2001), Valencia (2003), Guanajuato (2005), Chiang Mai (2007), Changhua (2009), Cluj (2012), Istanbul (2015), Newcastle(2017), and HeNan (2019) The conference will be dedicated to the memory of Professor Wataru Takahashi (1944–2020), Professor Kazimierz Goebel (1940–2022), and Professor William Art Kirk (1936-2022).

Logical Methods in Ramsey Theory and Related Topics July 10 - July 11, 2023, Pisa, Italy https://events.dm.unipi.it/e/ramsey2023pisa Dear all, We are happy to announce that registration for the upcoming event "Logical Methods in Ramsey Theory and Related Topics", which will be held in Pisa (Italy) from July 10th to July 11th, 2023, is now open. REGISTRATION: The deadline for registrations is ***SATURDAY, JUNE 10th***. There is no registration fee, but completing the registration form is mandatory. Students, early career researchers, and participants from disadvantaged countries can apply for support during the registration procedure. Participants traveling with young children can also apply for childcare support. Details for the registration and grant applications can be found on the conference website. The workshop is centered around the interplay between mathematical logic and combinatorics. Its main goals are: Disseminate information about various logical techniques used in several areas of combinatorics and related topics; Bring together researchers with different backgrounds, and encourage their collaborations and interactions, especially on topics connecting different areas of mathematics. The covered topics include (but are not limited to): Nonstandard methods in combinatorics and Ramsey Theory; Model-theoretical methods in density theory for semigroups; Reverse mathematics of combinatorial principles; Set theory and ultrafilter methods; Computational limits to finite provability and proof complexity; Quasi-orders and applications.

The conference continues a series of ring theory conferences in Graz from 2012, -14, -16, -18, and 2021. The main subjects include: Multiplicative ideal theory: ideal and module systems, star and semistar operations, Dedekind, Prüfer, Krull, and Mori rings and their generalizations, Noncommutative rings and algebras, Rings of integer-valued polynomials, Topological aspects in ring theory, Factorization theory in rings and semigroups, Direct-sum decomposition of modules.

2023. The school is oriented to young researchers, Ph.D. and postdoctoral students in Mathematics, Physics and Engineering, in particular those interested in focusing their research on geometric control and its applications to mechanical and electrical systems, and optimal control. Undegraduate students and master students are also welcome!!! This year the courses will be delivered by: Arjan van de Schaft (Groningen University, The Netherlands): The geometry of port-Hamiltonian systems. Alejandro Cabrera (Universidade Federal do Rio de Janeiro-UFRJ, Brasil Brazil): About the structure of local symplectic groupoids.

Students come from all over Europe to spend a week working in small groups on projects which are based on real-life problems. Each group is led by an ECMI instructor who introduces the problem – usually formulated in non-mathematical terms – on the first day, and then helps to guide the students to a solution during the week. The students present their results to the other groups on the last day and then write up their work as a report. The main aims of these Modelling Weeks are: train students in Mathematical Modelling and stimulate their collaboration and communication skills, in an international environment.
