### Teaching

Reads to RUDN University, Lomonosov Moscow State University, MEPhI students the following courses:

- Physics of nonlinear processes,
- Theoretical hydrodynamics,
- Equilibrium and stability of plasma.

**The author of the following course-books and study guides:**

- “The classical problem of the physics of hot plasmas”. V. I. Ilgisonis. / Study guide - M: Publishing house MEI, 2016, 326 p.|

The book deals with some of the key problems of physics of high-temperature plasma and magnetic fusion, which are considered to be classical and to which scientific thought returns from time to time due to the need to take into account new effects, expanding the scope of applicability, as well as due to progress in related scientific areas. Both well-known and original results obtained mostly in the works of the author are presented; some fairly universal mathematical methods and approaches are described, the productivity of which is demonstrated by relatively simple examples.

The summary of the semester lecture course is given, which is designed for senior students who have attended University courses of Mathematical analysis, Partial differential equations, Theoretical mechanics and have an idea about the methods of vector analysis and calculus of variations. The course is focused not on the subsequent solution of applied problems of hydromechanics, but on teaching future theoretical physicists the necessary basics of field theory, beyond the traditional University courses of hydrodynamics and electromagnetism. The study guide is prepared at the Department of Experimental Physics of the Faculty of Physical, Mathematical and Natural Sciences.

### Science

- A new direction in the study of Magnetohydrodynamic generator (MHD) stability of liquid media, based on a systematic account of the variation procedure set invariant, not reducible to ordinary Casimir invariants was developed; new symmetries and conservation laws were found; for toroidal topology flows, a sufficient stability condition was obtained, the closest to the necessary one of all known today.
- An exhaustive set of invariants of linearized dynamics of an ideal liquid or plasma in a magnetic field was discovered.
- The paradox of the continuous transition from multi-liquid to single-liquid MHD models, the essence of which is in the spontaneous symmetry breaking during such a transition, was solved.
- A new type of MHD instability characteristic of long magnetic systems was discovered and investigated, and a method for its suppression was proposed.
- A formalism of three-dimensional description of the drift dynamics of magnetized plasma was proposed and developed, taking into account the effects of the finite Larmor radius of ions; a new physically correct scheme of breaking the chain of moment equations was developed.
- A new magnetic flux-rotational instability was discovered, the threshold of which in the dipole field characteristic of astrophysical objects is an order of magnitude lower than the threshold of the magneto-rotational instability.
- The theory of low-frequency ideal MHD modes in axisymmetric toroidal systems with toroidal and poloidal plasma flows, describing the coupling of Alfven and slow (sound) modes that determine the continuous spectrum of the rotating plasma was constructed; unstable modes for plasma with supersonic poloidal rotation were found and conditions for their stabilization due to the effect of engagement with Alfven modes were found; the possibility of global modes was proved.
- The theory of gradient-drift instability in Hall-effect thrusters was constructed.
