It was found out in the first decade of this century that dependent type theory is no other than the internal language for (abstract) homotopy theory, just as the Mitchell-Benabou language is the internal language for topos theory. It is pleasing to note that the Freudenthal suspension theorem, the Blakers-Massey homotopy excision theorem, Whitehead's principle for n-types, the van Kampen theorem, and some other famous theorems are given new proofs within homotopy type theory., 数理科学IIIA(春学期) 数理科学IIIB(秋学期)}, title = {2016年度 数理科学III}, year = {2016}, yomi = {ニシムラ, ヒロカズ} }
