LINEAR ALGEBRA OF PASCAL MATRICES
LINDSAY YATES
Abstract. The famous Pascal’s triangle appears in many areas of
mathematics, such as number theory, combinatorics and algebra.
Pascal matrices are derived from this triangle of binomial coeffi-
cients, which create simplistic matrices with interesting properties.
We explore properties of these matrices and the inverse of the Pascal
matrix plus the identity matrix times any positive integer. We
further consider a unique matrix called the Stirling matrix, which
can be factorized in terms of the Pascal matrix.
