Ioan James
Ioan Mackenzie James FRS (23 May 1928 – 21 February 2025) was a British mathematician working in the field of topology, particularly in homotopy theory. Life and career James was born in Croydon, Surrey, England, and was educated at St Paul's School, London and Queen's College, Oxford. In 1953 he earned a D. Phil. from the University of Oxford for his thesis entitled ''Some problems in algebraic topology'', written under the direction of J. H. C. Whitehead. In 1957 he was appointed reader in pure mathematics, a post which he held until 1969. From 1959 until 1969 he was a senior research fellow at St John's College, Oxford. He held the Savilian Chair of Geometry at the University of Oxford from 1970 to 1995. He was a professor emeritus, and later an honorary fellow of St John's. He was elected a Fellow of the Royal Society in 1968. In 1978 the London Mathematical Society awarded him the Senior Whitehead Prize, which was established in honour of his doctoral supervisor, Wh ...

Savilian Chair Of Geometry
The position of Savilian Professor of Geometry was established at the University of Oxford in 1619. It was founded (at the same time as the Savilian Professorship of Astronomy) by Sir Henry Savile, a mathematician and classical scholar who was Warden of Merton College, Oxford, and Provost of Eton College, reacting to what has been described by one 20th-century mathematician as "the wretched state of mathematical studies in England" at that time. He appointed Henry Briggs as the first professor. Edward Titchmarsh (professor 1931–63) said when applying that he was not prepared to lecture on geometry, and the requirement was removed from the duties of the post to enable his appointment, although the title of the chair was not changed. The two Savilian chairs have been linked with professorial fellowships at New College, Oxford, since the late 19th century. Before then, for over 175 years until the middle of the 19th century, the geometry professors had an official residence adj ...

James Reduced Product
In topology, a branch of mathematics, the James reduced product or James construction ''J''(''X'') of a topological space ''X'' with given basepoint ''e'' is the quotient of the disjoint union of all powers ''X'', ''X''2, ''X''3, ... obtained by identifying points (''x''1,...,''x''''k''−1,''e'',''x''''k''+1,...,''x''''n'') with (''x''1,...,''x''''k''−1, ''x''''k''+1,...,''x''''n''). In other words, its underlying set is the free monoid generated by ''X'' (with unit ''e''). It was introduced by . For a connected CW complex ''X'', the James reduced product ''J''(''X'') has the same homotopy type as ΩΣ''X'', the loop space of the suspension Suspension or suspended may refer to: Science and engineering * Car suspension * Cell suspension or suspension culture, in biology * Guarded suspension, a software design pattern in concurrent programming suspending a method call and the calling ... of ''X''.
