Yurii Shirokov


Yurii Shirokov, was a writer, physicist, and professor. He graduated from Moscow State University in 1948. He worked in the same university, then in the Steklov Mathematical Institute. He wrote more than 100 scientific papers
and several monographs, among which the textbook "Nuclear Physics" is particularly relevant.

Algebra of generalized functions

Yu.Shirokov had constructed the Algebra of Generalized functions. Then it was applied to various systems

Classical and quantum mechanics

Shirokov was, perhaps, not the first to mention that quantum mechanics has many classical limits. The Planck constant appears in many relations, and there are many options to keep some of parameters as. The most known limiting cases of quantum mechanics are classical waves and Newtonian mechanics. Shirokov has systematised the construction of classical limits of quantum mechanics, see

Development of Shirokov's ideas

The most important ideas about the quantum mechanics and the theoretical physics in general formulated by
Shirokov are not yet developed. In particular, the field theory in terms of wave packets is not yet constructed.
