Ed(s): S. Watt
Event: ISSAC 91: International Symposium on Symbolic Algebraic Computation at Bonn, West Germany on July 15-17, 1991
TL;DR:
This work has tested DSC with a primality test for large integers and with a factorization algorithm for polynomials over large finite fields and observed significant speed-ups over executing the best-known methods on a single workstation computation.

On wiedemann's method of solving sparse linear systems
In H. F. Mattson, T. Mora, & T. R. N. Rao (Eds.), Applied Algebra, Algebraic Algorithms and Error-Correcting Codes (pp. 29–38).
Ed(s): H. Mattson, T. Mora & T. Rao
Event: 9th International Symposium, AAECC-9 at New Orleans, LA on October 7-11, 1991
TL;DR:
Douglas Wiedemann’s (1986) landmark approach to solving sparse linear systems over finite fields provides the symbolic counterpart to non-combinatorial numerical methods for solving sparselinear systems, such as the Lanczos or conjugate gradient method.

Partial Cylindrical Algebraic Decomposition for quantifier elimination
Journal of Symbolic Computation, 12(3), 299–328.
TL;DR:
This paper presents a method which intermingles CAD construction with truth evaluation so that parts of the CAD are constructed only as needed to further truth evaluation and aborts CAD construction as soon as no more truth evaluation is needed.

Processor efficient parallel solution of linear systems over an abstract field
Proceedings of the third annual ACM symposium on Parallel algorithms and architectures - SPAA '91. Presented at the the third annual ACM symposium.
Event: the third annual ACM symposium
TL;DR:
Parallel randomized algorithms are presented that solve n-dimensional systems of linear equations and compute inverses of n × n non-singular matrices over a field in O((log n)) time, where each time unit represents an arithmetic operation in the field generated by the matrix entries.
