Pafnuty Lvovich Chebyshev () ( – )〔(Pafnuty Lvovich Chebyshev – Britannica Online Encyclopedia )〕 was a Russian mathematician. His name can be alternatively transliterated as ''Chebychev'', ''Chebysheff'', ''Chebyshov''; or ''Tchebychev'', ''Tchebycheff'' (French transcriptions); or ''Tschebyschev'', ''Tschebyschef'', ''Tschebyscheff'' (German transcriptions). == Biography == One of nine children, Chebyshev was born in the central Russian village of Akatovo near Borovsk, to Agrafena Ivanova Pozniakova and Lev Pavlovich Chebyshev. His father had fought as an officer against Napoleon Bonaparte's invading army. Chebyshev was originally home schooled by his mother and his cousin, Avdotia Kvintillianova Soukhareva. He learned French early in life, which later helped him communicate with other mathematicians. A stunted leg prevented him from playing with other children, leading him to concentrate on his studies instead. Chebyshev studied at the college level at Moscow University, where he earned his bachelor's degree in 1841. At Moscow University, Chebyshev was a graduate student of Nikolai Brashman. After Chebyshev became a professor of mathematics in Moscow himself, his two most illustrious graduate students were Andrei Andreyevich Markov (the elder) and Aleksandr Lyapunov. Later he moved to St. Petersburg, where he founded one of the most important schools of mathematics in Russia, and there is today a research institute in mathematics called the Chebyshev Laboratory in that city. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pafnuty Chebyshev」の詳細全文を読む スポンサード リンク
