Maxim Lvovich Kontsevich (Russian: Макси́м Льво́вич Конце́вич ;   ; born 25 August 1964) is a Russian and French mathematician.
 He is a professor at the Institut des Hautes Études Scientifiques and a distinguished professor at the University of Miami.
 He received the Henri Poincaré Prize in 1997, the Fields Medal in 1998, the Crafoord Prize in 2008, the Shaw Prize and Fundamental Physics Prize in 2012, and the Breakthrough Prize in Mathematics in 2014.
In mathematics, a Poincaré–Steklov operator (after Henri Poincaré and Vladimir Steklov) maps the values of one boundary condition of the solution of an elliptic partial differential equation in a domain to the values of another boundary condition.
 Usually, either of the boundary conditions determines the solution.
 Thus, a Poincaré–Steklov operator encapsulates the boundary response of the system modelled by the partial differential equation.
 When the partial differential equation is discretized, for example by finite elements or finite differences, the discretization of the Poincaré–Steklov operator is the Schur complement obtained by eliminating all degrees of freedom inside the domain.
Seiringer studied physics at the University of Vienna, where in 1999 he acquired his diploma and in 2000 with Jakob Yngvason as thesis advisor attained a doctorate.
 In 2005 he attained his habilitation qualification at the University of Vienna.
 With a Schrödinger scholarship, he went in 2001 to Princeton University.
 There he became in 2003 assistant professor.
 Starting from 2010 he is an associate professor at McGill University.
 In addition he is extraordinarius professor at the University of Vienna.
 Seiringer made substantial progress in the mathematical theory of quantum gases and particularly Bose–Einstein condensate (BEC).
 He partly proved the existence of BEC for interacting boson gases in the Gross–Pitaevskii limit in collaboration with Elliott Lieb.
 They proved also superfluidity in this limit and derived the Gross–Pitaevskii equation in the special case of BEC in rotating containers.
 In 2009 Seiringer received the Henri Poincaré Prize.
Bifurcation theory is the mathematical study of changes in the qualitative or topological structure of a given family, such as the integral curves of a family of vector fields, and the solutions of a family of differential equations. Most commonly applied to the mathematical study of dynamical systems, a bifurcation occurs when a small smooth change made to the parameter values (the bifurcation parameters) of a system causes a sudden 'qualitative' or topological change in its behaviour.
 Bifurcations occur in both continuous systems (described by ODEs, DDEs or PDEs) and discrete systems (described by maps).
 The name "bifurcation" was first introduced by Henri Poincaré in 1885 in the first paper in mathematics showing such a behavior.
 Henri Poincaré also later named various types of stationary points and classified them.
In information theory, Linguistics and computer science, the Levenshtein distance is a string metric for measuring the difference between two sequences.
 Informally, the Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other.
 It is named after Vladimir Levenshtein, who considered this distance in 1965.
In mathematics, and in particular in the field of algebra, a Hilbert–Poincaré series (also known under the name Hilbert series), named after David Hilbert and Henri Poincaré, is an adaptation of the notion of dimension to the context of graded algebraic structures (where the dimension of the entire structure is often infinite).
 It is a formal power series in one indeterminate, say "t", where the coefficient of "t" gives the dimension (or rank) of the sub-structure of elements homogeneous of degree "n".
 It is closely related to the Hilbert polynomial in cases when the latter exists; however, the Hilbert–Poincaré series describes the rank in every degree, while the Hilbert polynomial describes it only in all but finitely many degrees, and therefore provides less information.
 In particular the Hilbert–Poincaré series cannot be deduced from the Hilbert polynomial even if the latter exists.
 In good cases, the Hilbert–Poincaré series can be expressed as a rational function of its argument "t".
In the mathematical theory of knots, the Kontsevich invariant, also known as the Kontsevich integral of an oriented framed link, is a universal Vassiliev invariant in the sense that any coefficient of the Kontsevich invariant is of a finite type, and conversely any finite type invariant can be presented as a linear combination of such coefficients.
 It was defined by Maxim Kontsevich.
The Annales Henri Poincaré ("A Journal of Theoretical and Mathematical Physics") is a peer-reviewed scientific journal which collects and publishes original research papers in the field of theoretical and mathematical physics.
 The emphasis is on "analytical theoretical and mathematical physics" in a broad sense.
 The journal is named in honor of Henri Poincaré and it succeeds two former journals, "Annales de l'Institut Henri Poincaré, physique théorique" and "Helvetica Physical Acta" (ISSN 0018-0238  ).
 It is published by Birkhäuser Verlag.
 Its first Chief Editor was Vincent Rivasseau and the current Chief Editor is Krysztof Gawedzki.
The Henri Poincaré Prize sponsored by the Daniel Iagolnitzer Foundation was created in 1997 to recognize outstanding contributions in mathematical physics, and contributions which lay the groundwork for novel developments in this broad field.
 The Prize is also created to recognize and support young people of exceptional promise who have already made outstanding contributions to the field of mathematical physics.
 The prize is awarded to three individuals every three years at the International Congress on Mathematical Physics.
 The prize committee is appointed by the International Association of Mathematical Physics (IAMP).
Vladimir Iosifovich Levenshtein (Russian: Влади́мир Ио́сифович Левенште́йн ; ] ; born 1935) is a Russian scientist who has done research in information theory, error-correcting codes, and combinatorial design.
 Among other contributions, he is known for the Levenshtein distance and a Levenshtein algorithm, which he developed in 1965.
