... computation of πn (X) can be broken into two parts: computing the rank of πn (X) and computing the torsion of πn (X). The second step is in general quite difficult. However, there is an elegant method for computing the first part for a wide class of spaces. The idea is to study πnQ (X) := πn (X) ⊗Z ...

The Fourier Transform can thus be generalized to sets other than the real line, such as the circle, the integers, and in fact any locally compact abeli ...

Lecture 10 homotopy Consider continuous maps from a topological

... Consider continuous maps from a topological space X to another topological space Y . Two such maps are called homotopic if one can continuously deform one to another. This provides a useful way to define topological invariants. In particular, when X is the n-sphere S n , the space of maps (modulo ho ...

... When the Boolean ring is a field of point sets, avb is the union of a and b. Furthermore, in any Boolean ring, avb enjoys the algebraic properties of point set union and will be referred to as the union of a and b even when a and b are not point sets. Regarding union and multiplication as the basic ...

Therefore we form its completion, Kp and consider K as a subfield. The philosophy (“local-global/Hasse principle”) is that the collecti ...

Homomorphism

In abstract algebra, a homomorphism is a structure-preserving map between two algebraic structures (such as groups, rings, or vector spaces). The word homomorphism comes from the ancient Greek language: ὁμός (homos) meaning ""same"" and μορφή (morphe) meaning ""form"" or ""shape"". Isomorphisms, automorphisms, and endomorphisms are special types of homomorphisms.
