Boju Jiang
Boju Jiang or Po-Chu Chiang, Chinese mathematician (Tianjin 04 September 1937 – Calculated the Nielsen numbers in a subgroup of fundamental group (1964) Verified the Nielsen fixed point conjecture (1980s) Clarified about the least number of fixed points among the maps in a homotopy class (1980s) Proved that the concordance group of algebraically slice knots is infinitely generated (1981) Gave an algebraic sufficient condition for the existence of periodic points of a prescribed pure period (1983) Developed Nielsen theory of periodic orbits (1996) With S. Wang & Y.Q. Wu showed that on many manifolds all orientation-preserving homeomorphisms are isotopic to fixed point free homeomorphisms (2000) With X.S. Lin, S. Wang & Y.Q. Wu developed various methods to detect the various achiralities of knots and links in S and gave a simple procedure for calculating the #-function in terms of a crossing change formula and its initial values (2002) With Y. Ni, S. Wang & Q. Zhou first established examples of non-fibred knots with property IE and non-fibred knots without property IE (2006) With H. Zheng deduced a trace formula for the computation of the forcing relation of braids (2008) With S. Wang & Q. Zhang introduced an alternative definition of fixed point class (2011) EPONYMY Jiang group Jiang subgroup Jiang spaces Jiang conditions (1963)
