Continuous quantities such as the ratio of circumference to diameter of a circle are as clearly known as discrete ones. The theory that mathematics was "the science of quantity" was once the leading philosophy of mathematics. The article looks at puzzles in the classification and epistemology of quantity
Numerical Computation of Exponential Functions of Nabla Fractional Calculus
In this article, we illustrate the asymptotic behaviour of exponential
functions of nabla fractional calculus. For this purpose, we propose a novel
matrix technique to compute these functions numerically
