Homotopy Theoryとは 意味・読み方・使い方

名詞

homotopy theory (countable かつ uncountable, 複数形 homotopy theories)

1. (mathematics) The systematic study of the situation of maps' having a homotopy between them; the study of equivalence classes (called homotopy classes) of maps.

   Homotopy theory originated as a topic in algebraic topology, but is now studied as an independent discipline in its own right, and as a tool in fields including category theory and algebraic geometry.

     This is our main result, deduced from the axioms of a cofibration category, which leads to many new theorems on the homotopy classification problems in topology and in various algebraic homotopy theories.

     They are also, from the viewpoint of homotopy theory, models for the homotopy theory of homotopy theories.
