An exploration of some properties of Kirby and Paris' hydra
|
|
|
|
|
battles, with the help of the Coq Proof assistant. This
|
|
|
|
|
development includes the study of several representations of
|
|
|
|
|
ordinal numbers, and a part of the so-called Ketonen and Solovay
|
|
|
|
|
machinery (combinatorial properties of epsilon0).
