- However, the importance of the singular homology groups is not limited to this.[1]
- now we come to another kind of homology groups, called singular homology groups of a topological space.[2]
- Singular homology groups were first defined by S. Lefschetz in 1933 and were perfected in their present form by S. Eilenberg (1913–1998) in the beginning of the 1940’s.[2]
- Singular theory is closely related to homotopy theory; there is a natural homomorphism from homotopy groups to singular homology groups.[3]
- In algebraic topology, a branch of mathematics, singular homology refers to the study of a certain set of algebraic invariants of a topological space X, the so-called homology groups H n ( X ) .[4]
- Singular homology is a particular example of a homology theory, which has now grown to be a rather broad collection of theories.[4]
- In brief, singular homology is constructed by taking maps of the standard n-simplex to a topological space, and composing them into formal sums, called singular chains.[4]
- A proof for the homotopy invariance of singular homology groups can be sketched as follows.[4]
- The main purpose of this book is to give a systematic treatment of singular homology and cohomology theory.[5]
- Singular homology and cohomology theory has been the subject of a number of textbooks in the last couple of decades, so the basic outline of the theory is fairly well established.[5]
- This corresponds to Eilenberg's innovation in the definition of singular homology and cohomology: one uses ordered p-simplexes rather than oriented p-simplexes.[6]
- They describe the singular homology groups and prove that they satisfy the Eilenberg-Steenrod axioms on the class of all topological spaces.[7]
- The zero'th singular homology group of a non-empty path-connected space is isomorphic to the group of integers.[8]
- For a map between topological spaces, definition of the induced chain map between the respective chain complexes, and the induced homomorphisms between singular homology groups.[8]
- Corollary: homotopy equivalent spaces have isomorphic singular homology groups (and in particular, contractible spaces have all reduced homology groups equal to 0).[8]
- I am having some difficulties understanding the difference between simplicial and singular homology.[9]
- My question is why this homology group equals the singular homology group?[10]
