Aleksei Pogorelov could refer to various individuals, as the name may not be widely recognized in public discourse. If you are referring to a specific person, context, or field (such as science, arts, sports, etc.

Alexander Friedmann was a Russian physicist and mathematician known for his pioneering work in cosmology during the early 20th century. He is best known for the Friedmann equations, which are central to modern cosmology and describe how the universe expands over time. Friedmann's equations emerged from his analysis of Einstein's general theory of relativity and addressed the dynamics of a homogeneous and isotropic universe. His work laid the groundwork for the Big Bang theory of the universe's origin.

Georgiy Shilov is not a widely recognized public figure or concept as of my last knowledge update in October 2023. It is possible that he could be a lesser-known individual, a fictional character, or involved in a niche area not covered in mainstream sources.

Georgy Adelson-Velsky (also known as Georgy Mikhailovich Adelson-Velsky) is a notable figure in the field of computer science, particularly known for his work in the area of data structures and algorithms. He is perhaps best known for co-developing the AVL tree, which is a type of self-balancing binary search tree that ensures the tree remains balanced after insertions and deletions.

Anatoli Vitushkin is a notable mathematician, primarily recognized for his work in the fields of complex analysis, partial differential equations, and symplectic geometry. He has made significant contributions to various areas of mathematics, particularly in relation to the geometric aspects of analysis and classical and modern analysis techniques.

Anatoly Maltsev is known as a Russian professional wrestler and coach, specializing in sambo and judo. He has contributed to the development of these sports in Russia and beyond.

Anatoly Shirshov is a Russian-American scientist best known for his contributions to various fields, including mathematics and computer science.

The number 158 is an integer that comes after 157 and before 159. It can be expressed in different contexts, such as: - **Mathematical properties**: It's an even number and can be factored into primes as \(2 \times 79\). - **Roman Numerals**: In Roman numerals, 158 is written as CLVIII. - **In other bases**: In binary, it is represented as 10011110.

Anton Zorich does not appear to be a widely recognized figure in popular culture, history, or scientific fields as of my last update in October 2023. It's possible that he could be a private individual, a character in fiction, or a figure emerging after that date.

As of my last update in October 2023, there is no widely recognized figure or event specifically known as "Arif Salimov." It's possible that he could be a private individual, a less prominent public figure, or relevant in a specific regional context or niche that hasn't gained widespread attention.

Ashot Petrosian is not widely recognized in historical or popular contexts, and there may be little publicly available information on an individual by that name as of my last update in October 2023.

He is best known for his work, the "Kama Sutra," which is an ancient text that discusses various aspects of love, relationships, and social dynamics, including sexual pleasure and intimacy.

Boris Galerkin was a Russian mathematician and engineer known for his contributions to the field of numerical analysis, particularly in the development of the Galerkin method. The Galerkin method is a technique used for converting a continuous operator problem (like differential equations) into a discrete problem, which can then be solved more easily using numerical methods. It involves approximating solutions using basis functions, which can significantly aid in solving partial differential equations and other complex problems in engineering and physics.

Boris Komrakov could refer to various individuals or concepts depending on the context, but he is most likely recognized as a mathematician known for his work in areas such as optimization theory and other mathematical fields.

Boris Levin could refer to different individuals or subjects, but there isn't a widely known or notable figure by that exact name as of my last update in October 2023.

As of my last update in October 2023, Boris Rufimovich Vainberg does not appear to be a widely recognized public figure, historical personality, or a prominent character in popular culture. It's possible that he may be a private individual or a lesser-known figure.
