Karol Borsuk (8 May 1905 – 24 January 1982) was a Polish mathematician. His main area of interest was topology . He made significant contributions to shape theory , a term which he coined.
A space is an absolute neighborhood retract for the class , written (), if is in and whenever is a closed subset of a space in , is a neighborhood retract of . Various classes C {\displaystyle {\mathcal {C}}} such as normal spaces have been considered in this definition, but the class M {\displaystyle {\mathcal {M}}} of metrizable spaces ...
[7] For all n for fields of revolution — shown by Boris Dekster (1995). [8] The problem was finally solved in 1993 by Jeff Kahn and Gil Kalai, who showed that the general answer to Borsuk's question is no. [9] They claim that their construction shows that n + 1 pieces do not suffice for n = 1325 and for each n > 2014.
Regret theory is a model in theoretical economics simultaneously developed in 1982 by Graham Loomes and Robert Sugden, [1] David E. Bell, [2] and Peter C. Fishburn. [3] Regret theory models choice under uncertainty taking into account the effect of anticipated regret. Subsequently, several other authors improved upon it. [4]
In mathematics, the Bing–Borsuk conjecture states that every -dimensional homogeneous absolute neighborhood retract space is a topological manifold. The conjecture has been proved for dimensions 1 and 2, and it is known that the 3-dimensional version of the conjecture implies the Poincaré conjecture .
Critical management studies (CMS) is a loose but extensive grouping of theoretically informed critiques of management, business and organisation, grounded originally in a critical theory perspective. Today it encompasses a wide range of perspectives that are critical of traditional theories of management and the business schools that generate ...
The Soft Systems Methodology was developed primarily by Peter Checkland, through 10 years of research with his colleagues, such as Brian Wilson.The method was derived from numerous earlier systems engineering processes, primarily from the fact traditional 'hard' systems thinking was not able to account for larger organisational issues, with many complex relationships.
