Development of fabrication facility for braid composite: structures.
This report gives the progress of work of the AR & DB
sponsored project during the period April 1936 to December 1987. Preliminary design of the braiding facility was carried out and a layout of the facility was carried. Specifications of the microcomputer based electronic controller required for the braiding facility were drafted and enquiries were sent for
the procurement of an experimental braiding unit, precision slide and the electronic controller of the braiding facility
LDB division algebras
An LDB division algebra is a triple in which and
are regular bilinear laws on the finite-dimensional non-zero vector
space such that is a scalar multiple of for all
vectors and of . This algebraic structure has been recently
discovered in the study of the critical case in Meshulam and \v Semrl's
estimate of the minimal rank in non-reflexive operator spaces.
In this article, we obtain a constructive description of all LDB division
algebras over an arbitrary field together with a reduction of the isotopy
problem to the similarity problem for specific types of quadratic forms over
the given field. In particular, it is shown that the dimension of an LDB
division algebra is always a power of , and that it belongs to
if the characteristic of the underlying field is not .Comment: 35 page
