Context_1 : In mathematics, specifically in local class field theory, the Hasse–Arf theorem is a result concerning jumps of the upper numbering filtration of the Galois group of a finite Galois extension. A special case of it when the residue fields are finite was originally proved by Helmut Hasse, and the general result was proved by Cahit Arf. Context_2 : In the mathematical field of knot theory, the Arf invariant of a knot, named after Cahit Arf, is a knot invariant obtained from a quadratic form associated to a Seifert surface. If "F" is a Seifert surface of a knot, then the homology group H("F", Z/2Z) has a quadratic form whose value is the number of full twists mod 2 in a neighborhood of an imbedded circle representing an element of the homology group. The Arf invariant of this quadratic form is the Arf invariant of the knot. Context_3 : Cahit Arf (] ; 11 October 1910 – 26 December 1997) was a Turkish mathematician. He is known for the Arf invariant of a quadratic form in characteristic 2 (applied in knot theory and surgery theory) in topology, the Hasse–Arf theorem in ramification theory, Arf semigroups, and Arf rings. Context_4 : The Kervaire invariant is an invariant of a framed (4"k"+2)-dimensional manifold that measures whether the manifold could be surgically converted into a sphere. This invariant evaluates to 0 if the manifold can be converted to a sphere, and 1 otherwise. This invariant was named after Michel Kervaire who built on work of Cahit Arf. Context_5 : The Academy Awards are given each year by the Academy of Motion Picture Arts and Sciences (AMPAS or the Academy) for the best films and achievements of the previous year. The Academy Award for Best Animated Feature is given each year for animated films. An animated feature is defined by the Academy as a film with a running time of more than 40 minutes in which characters' performances are created using a frame-by-frame technique, a significant number of the major characters are animated, and animation figures in no less than 75 percent of the running time. The Academy Award for Best Animated Feature was first given for films made in 2001. Context_6 : The ABA League MVP award, also known as the Adriatic League MVP award, is an annual award that is given to the most valuable player of the European regional Adriatic ABA League, which is the top-tier level professional basketball league for countries of the former Yugoslavia. The award has been given since the 2001–02 ABA League season. Context_7 : The Kardar–Parisi–Zhang (KPZ) equation (named after its creators Mehran Kardar, Giorgio Parisi, and Yi-Cheng Zhang) is a non-linear stochastic partial differential equation. It describes the temporal change of the height formula_1 at place formula_2 and time formula_3. It is formally Context_8 : The BBC Sports Personality of the Year is an awards ceremony that takes place annually in December. Devised by Paul Fox in 1954, it originally consisted of just one, the BBC Sports Personality of the Year Award. Several new awards have been introduced, and currently eight awards are presented. The first awards to be added were the Team of the Year and Overseas Personality awards, which were introduced in 1960. A Lifetime Achievement Award was first given in 1995 and again in 1996, and has been presented annually since 2001. In 1999, three more awards were introduced: the Helen Rollason Award, the Coach Award, and the Newcomer Award, which was renamed to Young Sports Personality of the Year in 2001. The newest is the Unsung Hero Award, first presented in 2003. In 2003, the 50th anniversary of the show was marked by a five-part series on BBC One called "Simply The Best – Sports Personality". It was presented by Gary Lineker and formed part of a public vote to determine a special Golden Sports Personality of the Year. That year Steve Rider and Martyn Smith wrote a book reflecting on the 50-year history of the award and the programme. The event was held outside London for the first time in 2006, when tickets were made available to the public. Context_9 : Mehran Kardar (Persian: مهران کاردار‎ ‎ ) is an Iranian born physicist and professor of physics at the Massachusetts Institute of Technology, and co-faculty at the New England Complex Systems Institute. He received his B.A. in physics from Cambridge University, and obtained his Ph.D. from MIT. Kardar is particularly known for the Kardar–Parisi–Zhang (KPZ) equation in theoretical physics, which has been named after him and collaborators. He was awarded a Guggenheim Fellowship in 2001. Context_10 : The ABA League Finals MVP award, also known as the Adriatic League Finals MVP award (formerly the Final Four MVP), is an annual award that is given to the most valuable player of the finals of the European regional Adriatic ABA League, which is the top-tier level professional basketball league for countries of the former Yugoslavia. The award has been given since the 2001–02 ABA League season. fact_1 : Cahit Arf (] ; 11 October 1910 – 26 December 1997) was a Turkish mathematician. fact_2 : Mehran Kardar (Persian: مهران کاردار‎ ‎ ) is an Iranian born physicist and professor of physics at the Massachusetts Institute of Technology, and co-faculty at the New England Complex Systems Institute. fact_3 :  He was awarded a Guggenheim Fellowship in 2001.
