Dennis Barden
Dennis Barden is a mathematician at the University of Cambridge working in the fields of geometry and topology. He is known for his classification of the simply connected compact 5-manifolds and, together with Barry Mazur and John R. Stallings, for having proved the s-cobordism theorem. Barden received his Ph.D. from Cambridge in 1964 under the supervision of C. T. C. Wall. Academic Positions Barden is a Life Fellow of Girton College, Cambridge and emeritus fellow of Pembroke College. In 1991, he became Director of Studies for mathematics at Pembroke College, succeeding Raymond Lickorish. He held the position until Michaelmas 2003, and in his time saw a great increase in the number of applicants for mathematics, with consistently high performances in Tripos exams. He remains an active supervisor A supervisor, or lead, (also known as foreman, boss, overseer, facilitator, monitor, area coordinator, line-manager or sometimes gaffer) is the job title of a lower-level mana ...

Girton College, Cambridge
Girton College is a constituent college of the University of Cambridge. The college was established in 1869 by Emily Davies and Barbara Bodichon as the first women's college at Cambridge. In 1948, it was granted full college status by the university, marking the official admittance of women to the university. In 1976, it was the first Cambridge women's college to become coeducational. Its sister college is Somerville College, one of the two Oxford colleges to first admit women. The main college site is situated on the outskirts of Girton, about northwest of the university town, and comprises of land. In a typical Victorian red-brick design, most was built by architect Alfred Waterhouse between 1872 and 1887. Among Girton's notable alumni are Queen Margrethe II, former UK Supreme Court President Lady Hale, ''HuffPost'' co-founder Arianna Huffington, the comedian/author Sandi Toksvig, the comedian/broadcaster/GP Phil Hammond, the economist Joan Robinson, and the a ...

Annals Of Mathematics
The ''Annals of Mathematics'' is a mathematical journal published every two months by Princeton University and the Institute for Advanced Study. History The journal was established as ''The Analyst'' in 1874 and with Joel E. Hendricks as the founding editor-in-chief. It was "intended to afford a medium for the presentation and analysis of any and all questions of interest or importance in pure and applied Mathematics, embracing especially all new and interesting discoveries in theoretical and practical astronomy, mechanical philosophy, and engineering". It was published in Des Moines, Iowa, and was the earliest American mathematics journal to be published continuously for more than a year or two. This incarnation of the journal ceased publication after its tenth year, in 1883, giving as an explanation Hendricks' declining health, but Hendricks made arrangements to have it taken over by new management, and it was continued from March 1884 as the ''Annals of Mathematics''.

Tutorial System
The tutorial system is a method of university education where the main teaching method is regular, very small group sessions. These are the core teaching sessions of a degree, and are supplemented by lectures, practicals and larger group classes. This system is found at the collegiate universities of University of Oxford, Oxford and University of Cambridge, Cambridge, although other universities use this method to various degrees. Oxbridge The Oxbridge tutorial system was established in the 1800s at the University of Oxford and the University of Cambridge in the United Kingdom. It is still practised today, and consists of undergraduate students being taught by Fellow (Oxbridge), college fellows, or sometimes doctoral students and post-docs) in groups of one to three on a weekly basis. These sessions are called "tutorials" at Oxford and "supervisions" at Cambridge, and are the central method of teaching at those universities. The student is required to undertake preparatory work fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tripos
TRIPOS (''TRIvial Portable Operating System'') is a computer operating system. Development started in 1976 at the Computer Laboratory of Cambridge University and it was headed by Dr. Martin Richards. The first version appeared in January 1978 and it originally ran on a PDP-11. Later it was ported to the Computer Automation LSI4 and the Data General Nova. Work on a Motorola 68000 version started in 1981 at the University of Bath. MetaComCo acquired the rights to the 68000 version and continued development until TRIPOS was chosen by Commodore in March 1985 to form part of an operating system for their new Amiga computer; it was also used at Cambridge as part of the Cambridge Distributed Computing System. Students in the Computer Science department at Cambridge affectionately refer to TRIPOS as the ''Terribly Reliable, Incredibly Portable Operating System''. The name TRIPOS also refers to the Tripos system of undergraduate courses and examinations, which is unique to Cam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembroke College, Cambridge
Pembroke College is a constituent college of the University of Cambridge, England. The college is the third-oldest college of the university and has over 700 students and fellows. It is one of the university's larger colleges, with buildings from almost every century since its founding, as well as extensive gardens. Its members are termed "Valencians". The college's current master is Chris Smith, Baron Smith of Finsbury. Pembroke has a level of academic performance among the highest of all the Cambridge colleges; in 2013, 2014, 2016, and 2018 Pembroke was placed second in the Tompkins Table. Pembroke contains the first chapel designed by Sir Christopher Wren and is one of only six Cambridge colleges to have educated a British prime minister, in Pembroke's case William Pitt the Younger. The college library, with a Victorian neo-gothic clock tower, has an original copy of the first encyclopaedia to contain printed diagrams. History Marie de St Pol, Countess of Pembroke (1303� ...

S-cobordism Theorem
In geometric topology and differential topology, an (''n'' + 1)-dimensional cobordism ''W'' between ''n''-dimensional manifolds ''M'' and ''N'' is an ''h''-cobordism (the ''h'' stands for homotopy equivalence) if the inclusion maps : M \hookrightarrow W \quad\mbox\quad N \hookrightarrow W are homotopy equivalences. The ''h''-cobordism theorem gives sufficient conditions for an ''h''-cobordism to be trivial, i.e., to be C-isomorphic to the cylinder ''M'' × , 1 Here C refers to any of the categories of smooth, piecewise linear, or topological manifolds. The theorem was first proved by Stephen Smale for which he received the Fields Medal and is a fundamental result in the theory of high-dimensional manifolds. For a start, it almost immediately proves the generalized Poincaré conjecture. Background Before Smale proved this theorem, mathematicians became stuck while trying to understand manifolds of dimension 3 or 4, and assumed that the higher-dimensional cases were ...
