Viktor Buchstaber
Victor Matveevich Buchstaber (russian: Виктор Матвеевич Бухштабер, born 1 April 1943, Tashkent, Soviet Union) is a Soviet Union, Soviet and Russian mathematician known for his work on algebraic topology, homotopy, homotopy theory, and mathematical physics. Work Buchstaber's first research work was in cobordism theory. He calculated the differential in the Atiyah-Hirzebruch spectral sequence in K-theory and complex cobordism theory, constructed Chern-Dold characters and the universal Todd genus in cobordism, and gave an alternative effective solution of the Milnor-Hirzebruch problem. He went on to develop a theory of double-valued formal groups that led to the calculation of cobordism rings of complex manifolds having symplectic coverings and to the explicit construction of what are now known as ''Buchstaber manifolds''. He devised filtrations in Hopf algebras and the ''Buchstaber spectral sequence'', which were successfully applied to the calculation of ...

Tashkent
Tashkent (, uz, Toshkent, Тошкент/, ) (from russian: Ташкент), or Toshkent (; ), also historically known as Chach is the capital and largest city of Uzbekistan. It is the most populous city in Central Asia, with a population of 2,909,500 (2022). It is in northeastern Uzbekistan, near the border with Kazakhstan. Tashkent comes from the Turkic ''tash'' and ''kent'', literally translated as "Stone City" or "City of Stones". Before Islamic influence started in the mid-8th century AD, Tashkent was influenced by the Sogdian and Turkic cultures. After Genghis Khan destroyed it in 1219, it was rebuilt and profited from the Silk Road. From the 18th to the 19th century, the city became an independent city-state, before being re-conquered by the Khanate of Kokand. In 1865, Tashkent fell to the Russian Empire; it became the capital of Russian Turkestan. In Soviet times, it witnessed major growth and demographic changes due to forced deportations from throughout the Sov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
