One-Parameter Semigroups of Operators (OPSO 2023) (February 27–March 3, 2023, Online)
International Laboratory of Dynamical Systems and Applications cordially invites researchers and students to take part in the One-Parameter Semigroups of Operators (OPSO 2023) Conference held by HSE University online. The conference is devoted to study of one-parameter families of mappings and measures, interplay between linear dynamical systems in infinite-dimensional spaces and nonlinear dynamical systems in finite-dimensional spaces, quantum evolution, stochastic processes and related topics.
Conference welcomes both communications on new research results as well as overview and biographical talks. Speakers can expect that the definition of a C0-semigroup is known for the attendees, but other definitions are better to be given, and the talk should be accessible to unprepared audience because the conference usually attracts rather many students. All talks are given online. If the speaker agrees, the recording of the talk is uploaded to YouTube.
The conference will cover the following topics:
- One-parameter (semi)groups of linear operators, their applications and generalizations;
- Nonlinear (semi)flows: ergodicity, chaos and other dynamical phenomena;
- Interplay between linear infinite-dimensional systems and nonlinear finite-dimensional systems;
- Quantum physics, quantum information and quantum dynamical semigroups;
- Infinite-dimensional analysis, probability, stochastic processes and financial mathematics;
- Related topics.
This is the third time when the worldwide community of researchers interested in operator semigroups gathers together for fruitful discussions on the online OPSO conference.
