Title : Investigating The Algebraic Structure of Dihomotopy Types
Abstract :
This presentation is the sequel of a paper published in GETCO'00
proceedings where a research program to construct an appropriate
algebraic setting for the study of deformations of higher
dimensional automata was sketched. This paper will be focused
precisely on detailing some of its aspects. The main idea is that
the category of homotopy types can be embedded in a new category of
dihomotopy types, the embedding being realized by the Globe functor.
In this latter category, isomorphism classes of objects are exactly
higher dimensional automata up to deformations leaving invariant
their computer scientific properties as presence or not of deadlocks
(or everything similar or related). Some hints to study the
algebraic structure of dihomotopy types are given, in particular a
rule to decide whether a statement/notion concerning dihomotopy
types is or not the lifting of another statement/notion concerning
homotopy types. This rule does not enable to guess what is the
lifting of a given notion/statement, it only enables to make the
verification, once the lifting has been found.
