📰 Bardin studied mathematics at Moscow University, and completed his Candidate of Sciences degree in 1920 under Pavel Alexandrov, followed by a doctoral dissertation in 1923 on singularities of three-dimensional algebraic surfaces. He worked as a lecturer in Moscow University until 1940, then became effective head of the mathematics department, succeeding Alexandrov in 1947. In 1950 he became Professor at the Steklov Mathematical Institute and Director of its Moscow branch. During his retirement (1964–74) he worked at the Institute of Mathematics, Russian Academy of Sciences. 📰 He was awarded the Stalin Prize in 1941 and Again in 1951, the Lenin Prize in 1957, and was elected an corresponding member of the USSR Academy of Sciences in 1957, and a full member in 1961. 📰 In the 1940s Bardin began research on singularities using algebraic methods. He studied the equations that determine these singularities, proved individual finite classifications, and constructed families of singularities after systematic classification, mainly of isolated singularities. He established conjectures (later proved by Arnold) relating both classes of normal quasi-convex singularities to analytic classes. Bardin's own classifications were later found incomplete due to topological or differential subtleties, but stimulated developments in singularity theory. He was the first to use motivating examples of analytic classifications to develop formal algebraic categories, distinguishing equitional and analytic (geometric) notions. He also influenced the development of category theory, discussing Ricci equivalence (related to homological algebra) and homotopical aspects of classifications. Before and after his death Bardin continued to write about singularities, concluding a long series of papers with Coxeter and Arnold. Bardin supported rising mathematicians, including Arnold, Vladimir Arnold, Boris Gorshenin, and others. 📰 5 Log In Now And Transform Your Workflowdont Miss This Activebuilding Hacks Lucky You 5891568 📰 Skull Headphones 7283297 📰 Uber Stocks 609718 📰 These Stovepipe Jeans Are Set To Take Over Your Closet Hook Your Style Today 3740186 📰 Unexpected Sharepoint News November 2025 The System Wont Lieget Alerted Now 3781269 📰 Limbo Download 8055118 📰 American Dollar To Rm What It Means For Your Wallet By 2025 5274523 📰 Kirishima Mha 7187057 📰 Lion Os Secret Terror Experts Weigh In On The Awe Striking Lion Man Hybrid 4857087 📰 Black Guy Meme That Made Millionsyou Wont Believe What Happened Next 6199510 📰 The Untold Journey Of Edward Elric Why Its Gripping Every Moment Ever 6324228 📰 Fire Chief Swears By Fire Chief Arborvitaethis Green Giant Could Save Lives 3912252 📰 Goodyears Stock Just Breaks Xxis This The Start Of A Big Investment Boom 8250646 📰 Wendyswantstoknow 7244263 📰 Sound Connect App 2941149
