SUMMARY:Foundations of Computational Mathematics 2026
DESCRIPTION:FoCM 2026 will be the 10th iteration of the FoCM society‘s successful conference series\, following the initial meeting in Park City in 1995 and 9 subsequent conferences all over the globe.\nEach of the previous conferences has attracted several hundred participants from all branches of mathematics that impinge on computation in the broadest sense.\nThe event’s 2026 edition will be hosted by the University of Vienna’s Faculty of Mathematics. \nFoCM conferences are usually organized as follows: mornings are devoted to plenary talks and afternoons to parallel workshops.\nThe conference is divided into three periods of three days\, and each workshop takes place during one of these periods.\nThe spirit of FoCM is that participants are encouraged to come for the whole duration of the conference and to attend talks in different workshops. Poster sessions are also organized by each workshop.

SUMMARY:ORTHONET winter events 2025
DESCRIPTION:The ORTHONET Network brings together researchers focused on orthogonal polynomials and special functions\, exploring their deep connections with fields such as approximation theory\, operator theory\, number theory\, information theory\, Fourier series\, numerical analysis\, integrable systems and probability. This cross-disciplinary approach extends beyond pure mathematics\, finding applications in mathematical physics\, science\, and technology. \nA core goal of ORTHONET is to foster collaboration within the Spanish scientific community\, uniting those who specialize in orthogonality and its diverse applications. By doing so\, the network seeks to raise the quality and impact of research in this area. Another priority is facilitating the transfer of expertise to other scientific and technological fields where orthogonality offers untapped potential. \nThe ORTHONET network receives funding through project RED2022-134580-T\, as part of the National Program aimed at advancing scientific and technical research and promoting its transfer. This initiative is supported by the 2021-2023 State Plan for Scientific\, Technical\, and Innovation Research\, under the Ministry of Science\, Innovation\, and Universities. \nThe Organizing Committee gratefully acknowledges the support of the Faculty of Physical Sciences for providing the infrastructure. \n \nSchool Programme\n\nDates: December 16-19\nVenue: Faculty of Physical Sciences\, UCM\, Theoretical Physics Department Seminar Room\, second floor (capacity: 25 people)\nProfessors:\n\nMaría Ángeles García Ferrero (Mini-Course: Exceptional orthogonal polynomials and Darboux transformations)\nAndrei Martínez-Finkelshtein (Mini-Course: Logarithmic Potential Theory)\nWalter Van Assche (Mini-Course: Multiple Orthogonal Polynomials—Theory and Applications)\n\n\nSchedule:\n\nFirst morning session: 9:00 AM – 11:00 AM. Walter Van Assche: Multiple Orthogonal Polynomials—Theory and Applications\nCofee break: 11:00 AM- 11:30 AM\nSecond morning session: 11:30 AM – 1:30 PM. Andrei Martínez-Finkelshtein: Logarithmic Potential Theory\nLunch: 1:30 PM – 3:00 PM\nAfternoon session: 3:00 PM – 5:00 PM. María Ángeles García Ferrero: Exceptional orthogonal polynomials and Darboux transformations\nDiscusion: 5:00 PM- 6:00 PM\n\n\nEach professor will teach four two-hour classes.

SUMMARY:IV Escuela Orthonet
DESCRIPTION:En el marco de la red Orthonet tendrá lugar la cuarta escuela ORTHONET-2024 donde se tratarán temas afines a la red: polinomios ortogonales\, teoría de la aproximación\, y algunas de sus aplicaciones. Esta escuela es la continuación de las tres previas que tuvieron lugar en Sevilla en 2016\, Madrid en 2017\, y Bilbao en 2018. \nLa cuarta escuela tendrá lugar en la Facultad de Ciencia y Tecnología de la Universidad de La Rioja\, Logroño\, durante durante los días 6 al 9 de mayo de 2024. \nLa escuela constará de tres minicursos cursos y varias sesiones de trabajo. \n  \n\n \nCursos:\n  \n\n  \n\nTítulo: Orthogonality and bispectrality. Profesor: Antonio J. Durán.Abstract: In these lectures\, we will consider two important extensions of the classical and classical discrete orthogonal polynomials. On the one hand\, Krall or bispectral polynomials which\, besides the orthogonality\, are also common eigenfunctions of higher-order differential or difference operators; on the other hand\, exceptional polynomials which have recently appeared in connection with quantum mechanics models associated to certain rational perturbations of the classical potentials. We also explore the relationship between both extensions and how they can be used to expand the Askey tableau.\nTítulo: Orthogonal polynomials and representation theory. Profesor: Maarten van Pruijssen.Abstract: In this course we describe how matrix-valued polynomials arise naturally in the context of multiplicity free representation theory of compact groups. We will see how the relation to group representations gives rise to explicit results for the matrix-valued polynomials; orthogonality\, recursion relations\, differential operators\, etc. In the scalar-case this amounts to the identification of the zonal spherical functions with the Jacobi polynomials in rank one and with Heckman-Opdam polynomials in general and we will see how this generalizes to the matrix case. The emphasis is on specific examples and the required representation theory will be recalled.\nTítulo: An introduction to matrix valued orthogonal polynomials. Profesor: Pablo Roman.Abstract: The goal of this course is to present an introduction to the theory of matrix valued orthogonal polynomials. The theory was initiated by Krein in the 1940s and has connections with a broad range of branches of mathematics\, such as harmonic analysis\, approximation theory\, spectral theory\, mathematical physics\, etc. The course aims at developing an understanding of the basic notions of matrix orthogonality and the main structural and analytic properties of matrix orthogonal polynomials. There will be emphasis on the study of matrix valued differential and difference operators having the polynomials as eigenfunctions. The Riemann-Hilbert formulation for matrix valued orthogonal polynomials will be discussed. The theoretical concepts will be illustrated with applications to integrable systems.\n\n  \n  \n\nLa apertura del curso tendrá lugar el lunes 9 de mayo a las 9:00 horas y la clausura el jueves 9 a las 18:00. \nHorario de las sesiones:\n  \n\n\n\n\nLunes \n\n\nMartes \n\n\nMiércoles \n\n\nJueves \n\n\n\n\nDurán \n9:15-11:15 \n\n\nDurán \n9:15-11:15 \n\n\nDurán \n9:15-11:15 \n\n\nDurán \n9:15-11:15 \n\n\n\n\nCoffe-Break 11:15-11:45 \n\n\nCoffe-Break \n11:15-11:45 \n\n\nCoffe-Break \n11:15-11:45 \n\n\nCoffe-Break \n11:15-11:45 \n\n\n\n\nRoman \n11:45-13:45 \n\n\nRoman \n11:45-13:45 \n\n\nRoman \n11:45-13:45 \n\n\nRoman \n11:45-13:45 \n\n\n\n\nLunch \n14:00-16:00 \n\n\nLunch \n14:00-16:00 \n\n\nLunch \n14:00-16:00 \n\n\nLunch \n14:00-16:00 \n\n\n\n\nvan Pruijssen \n16:00-18:00 \n\n\nvan Pruijssen \n16:00-18:00 \n\n\nvan Pruijssen \n16:00-18:00 \n\n\nvan Pruijssen \n16:00-18:00 \n\n\n\n\n  \n\nOrganización: La escuela está organizada por el Prof. Óscar Ciaurri (director).
