ABSTRACT.
This paper derives inequalities for general linear recurrences. Optimal
bounds for solutions to the recurrence are obtained when the coefficients of
the recursion lie in intervals that include zero. An important aspect of the
derived bounds is that they are easily computable. The results bound
solutions of triangular matrix equations and coefficients of ratios of power
series.
Key words:
Recurrence, Restricted Coefficients, Power Series, Triangular Matrices.
