27. As promised in 22, Part I ('Roy. Soc. Proc.,’ vol. 52, p. 504), I will now first show how the formulae for the Fourier-Bessel function in rising and descending powers of the variable may be algebraically harmonized, without analytical operations. The algebraical conversion is to be effected by means of the generalized exponential theorem, 20. It was, indeed, used in 22 to generalize the ascending form of the function in question; but that use was analytical. At present it is to be…

The Heaviside expansion theorem is widely known and used in circuit theory. It is, in fact, a mathematical result with a long history. Its discovery forms a chapter in the history of differential…

Heaviside's operational calculus and the attempts to rigorise it

The theory presented is sufficiently general to encompass all singularity functions of the impulsive type without the need for abstract mathematics to solve lumped linear circuits and other differential systems without leaving the time domain.

A Noncommutative Algebraic Operational Calculus for Boundary Problems

- MathematicsMath. Comput. Sci.

A left ring of fractions over a certain ring of boundary problems for linear ordinary differential equations allows to build a symbolic calculus in the style of Heaviside and Mikusiński, but with the added benefit of incorporating boundary conditions where the traditional calculi allow only initial conditions.
