Tensor Algebras, Symmetric Algebras and Exterior Algebras
We begin by defining tensor products of vector spaces over a field and then we investigate some basic properties of these tensors, in particular the existence of bases and duality. After this, we investigate special kinds of tensors, namely, symmetric tensors and skew-symmetric tensors. Tensor products of modules over a commutative ring with identity will be discussed very briefly. They show up...
متن کاملalgebras , operads and tensor categories
We study the operadic and categorical formulations of (conformal) full field algebras. In particular, we show that a grading-restricted R × R-graded full field algebra is equivalent to an algebra over a partial operad constructed from spheres with punctures and local coordinates. This result is generalized to conformal full field algebras over V L ⊗ V R , where V L and V R are two vertex operat...

متن کاملTensor algebras and combinatorial parameters
For any real inner product space V , let T (V ) denote its tensor algebra. We give a theorem giving conditions under which a real-valued algebra homomorphism from certain subalgebras of T (V ) can be extended to T (V ). The main applications are characterizations of combinatorial parameters by means of ‘reflection positivity’. The proof method follows mainly that of Szegedy [4], whose theorem i...
متن کاملArens-irregularity of tensor product of Banach algebras
We introduce Banach algebras arising from tensor norms. By these Banach algebras we make Arensregular Banach algebras such that tensor product becomes irregular, where is tensor norm. Weillustrate injective tensor product, does not preserve bounded approximate identity and it is notalgebra norm.
