[B] The Concept of Spectrum of functions  Ramsey type statements in

[19], [24], [28], [30], [31], [32],
[34], [36], [37], [51], [69]; [86], [129], [139], [145]. Some crucial papers: 

[19]  1968,  the concept of spectrum is formally introduced (there are two forms; finite dimensional and infinite dimensional);  
[24]  1969,  the conjecture of Spectrum/Distortion is formally introduced and the idea of "stabilization" of functions on the sphere is discussed.  
[31]  1971,  Geometry of Infinite dimensional sphere and different asymptotic modulii are studied with a chapter on Spectrum..  
[32]  1971,  the start of the method of Concentration; but the the leading point is the search of spectrum of a good (say, Lipschitz) function..  
[34]  1971,  the concept of Spectrum extended to different manifolds and the connection with the Ramsey type facts in Combinatorics became transparent (however, only after the paper by Graham,R.L.; Leeb,K.; Rothschild, B. L., Ramsey's theorem for a class of categories. Advances in Math. 8, 417433,1972, appeared).  
[51]  1983, joint with Gromov; in addition to remarks written in A, more examples of "spectrum type" are presented here. The connection with fixed point property is mentioned in the first time.  
[69]  1987,  connection between Concentration, Spectrum and Fixed point theorems is explicitely exibit.  
[86]  1988,  a survey on old and new connections and results on Concentration and Spectrum.
