The Department of Landscape Design and Sustainable Ecosystems, Research center «Smart Technologies for Sustainable Development of the Urban Environment in the Global Change» Agrarian and Technological Institute RUDN University organizes an international scientific seminar "Monitoring of urban green infrastructure", which will be held on September 30. Due to restrictions related to the coronavirus, the event will take place online on the Microsoft Teams platform. The Seminar starts at 15:30 Moscow time. The working language is English.

One of the most significant scientific discoveries of recent decades is the discovery of deterministic chaos in dynamical systems.

Quantum graphs with infinitely many vertices and edges will be discussed.

At the moment, there are mobile devices that can read a single-channel ECG. These devices can be used for preliminary screening of various diseases. This report will talk about various methods that allow you to classify single-channel mobile ECGs with a fairly high quality. Many of these methods and improvements to them were proposed for the first time by the author of this report. The report highlights the strengths and weaknesses of the proposed methods. It is worth noting that all the methods considered can be generalized to work with traditional ECGs.

The Lavrentiev phenomenon is the difference between the minimums/minimizers of integral functionals when minimized over "wide" and "narrow" Sobolev spaces. In particular, the "narrow" space can be understood as the closure of smooth function in the "wide" Sobolev space (the natural energy space of functions, where the integral functional is finite), and in this case the Lavrentiev phenomenon happens when smooth functions are not dense in the "wide" Sobolev space.

A two-dimensional system of the Vlasov-Poisson equations for a two-component plasma in a bounded domain is considered. It is shown that in the neighborhood of a stationary solution of such a system with zero potential there are stationary solutions with non-zero potential of a self-consistent electric field.

The subject of the talk are biological and biomedical problems that we model using systems of chemotactic equations with cross-diffusion terms. I will present recent results related to quasi-periodic behavior of biological system arising from chemotactic framework of Keller-Segel.
