On the Complexity of Bilinear Forms with Commutativity

SIAM Journal on Computing, 1979
We consider the general problem of computing sets of bilinear forms in commuting indeter-minates. We develop lower bound techniques which seem to be more powerful than those already known in the literature. We show that duality theory as it is known for bilinear forms with noncommuting indeter-minates does not hold in the commutative case; we prove ...

Bilinear transformations and forms

1995
Bilinear transformations and bilinear forms are introduced and studied. Their matrix representation, and especially the representation of symmetric bilinear forms, is presented. Orthogonality relative to a bilinear form is considered. These notions are then used to define the tensor product of vector spaces, and the properties of the tensor product are

On Some Invariants of a Bilinear Form

Canadian Mathematical Bulletin, 1961
Let E be a finite dimensional vector space over an arbitrary field. In E a bilinear form is given. It associates with every sub s pa ce V its right orthogonal sub space V* and its left orthogonal subspace *V. In general we cannot expect that dim V* = dim *V. However this relation will hold in some interesting special cases.

Anticodes for the Grassman and bilinear forms graphs

Designs, Codes and Cryptography, 1995
This paper presents anticodes in Grassmann graphs and bilinear forms graphs. A new proof of the result due to Chihara viz. ``Many infinite families of classical distance-regular graphs have no nontrivial perfect codes, including the Grassmann graphs and the bilinear forms graphs'' has been given for these two families.

Linear Forms and Bilinear Forms

2015
In this chapter we study different classes of maps between one or two K-vector spaces and the one dimensional K-vector space defined by the field K itself. These maps play an important role in many areas of Mathematics, including Analysis, Functional Analysis and the solution of differential equations.
