WebHow to tackle 'dot' product for spin matrices. I read a textbook today on quantum mechanics regarding the Pauli spin matrices for two particles, it gives the Hamiltonian as H = α[σ1z + σ2z] + γ→σ1 ⋅ →σ2 where →σ1 and →σ2 are the Pauli spin matrices for two particles separately. I think σz is the z component, I found that σz ... WebMar 24, 2024 · A transformation of the variables of a tensor changes the tensor into another whose components are linear homogeneous functions of the components of the original tensor. A tensor space of type can be described as a vector space tensor product between copies of vector fields and copies of the dual vector fields, i.e., one-forms. For …

The tensor product of two fields is sometimes a field, and often a direct product of fields; In some cases, it can contain non-zero nilpotent elements. The tensor product of two fields expresses in a single structure the different way to embed the two fields in a common extension field. See more In mathematics, the tensor product of two fields is their tensor product as algebras over a common subfield. If no subfield is explicitly specified, the two fields must have the same characteristic and the common subfield is … See more The structure of the ring can be analysed by considering all ways of embedding both K and L in some field extension of N. The construction here assumes the common subfield N; but does not assume a priori that K and L are subfields of some field M (thus getting round … See more This gives a general picture, and indeed a way of developing Galois theory (along lines exploited in Grothendieck's Galois theory). It can be shown that for separable extensions the … See more First, one defines the notion of the compositum of fields. This construction occurs frequently in field theory.
