Chernoff Approximations 2025

The international scientific conference Chernoff Approximations 2025 will be held on November 22, 2025. The conference will be held in a hybrid format: participation is possible online, as well as in person in Moscow and Nizhny Novgorod. If you want to organise a space for in-person participation in your city, please let us know and we will add this information to the conference website.

In his PhD thesis defended at Harvard University in 1968, American mathematician Paul Chernoff proposed a method for approximately finding semigroups of operators—a method which now bears his name. Today, Chernoff approximations are a flexible, powerful, and in-demand tool of functional analysis with numerous applications in modern mathematics and mathematical physics. The conference is a place for exchanging opinions and the latest scientific results related to Chernoff approximations.

Thematic sections of the conference:

• Chernoff's theorem, its generalisations and variants
• Chernoff functions in specific cases
• Theoretical applications of Chernoff's theorem
• Practical calculation of Chernoff approximations
• Rate of convergence of Chernoff approximations
• Related questions and open problems

The working languages ​​of the conference are English and Russian.

There is no registration fee.

Please inform the organisers about your participation by November 1 by email: ivremizov@yandex.ru

We invite you, your students, and colleagues to participate as listeners and speakers. Please tell anyone who might be interested about the conference!
