Stevo TodorcevicOnly full exposition of the method since its invention in the early 1980s.In recent times the method is finding remarkable new appplications.Includes supplementary material:

Walks on Countable Ordinals,al essence can be reformulated as problems about ., which is in some sense the smallest uncountable structure. What we mean by ‘structure’ is . together with a system . (. < .) of fundamental sequences, i.e., a system with the following two properties:

The Square-bracket Operation on Countable Ordinals,(..) for all . < .. Recall also the notion of the . of the minimal walk, . the finite set of places visited in the minimal walk from . to .. The following simple fact about the upper trace lies at the heart of all known definitions of square-bracket operations, not only on . but also at higher cardinalities.

Unbounded Functions,essarily coherent, then it is natural to define the corresponding mapping . as follows: . with the boundary value .(.) = 0 for all . < ., a definition that is slightly different from the one given above in (7.3.2) above. Clearly, . and so, using Lemma 6.2.1, we have the following fact.
