The rigidity of a matrix is defined to be the number of entries in the matrix that have to be changed in order to reduce its rank below a certain value. Using a simple combinatorial lemma, we show that one must alter at least c( n\*/r) log( n/r) entries of an (n x n)-Cauchy matrix to reduce its rank

One of the uses of the Rorschach test is to evaluate the extent of the rigidity and flexibility of an individual's defense system and his approach to life's problems. I n a recent experiment on the effects of a verbal set on Rorschach test performance of neurotics(2), the writer had the opportunity
This paper presents a matrix analysis of the Dual Reciprocity Boundary Element Method (DRM) applying to several kinds of boundary value problems. This method demonstrates how to reduce the storage and computation for the Stiffness matrix and its component matrices.
In this paper we prove the equivalence of some conjectures on the generic rigidity bar frameworks in 3-space.
