MHB Laplace transform of a series in time t

[sarrah1]

Hi

I have a series

${f}_{1}$ , ${f}_{2}$, ... that are all a functions of a variable $t$

I am seeking a point-wise convergence. to investigate the convergence of the series I took Laplace transform. If I can find a condition on the Laplace variable $s$, can I find the condition of convergence of the series on $t$.

is it normal to investigate convergence of series via Laplace transform ?
thanks

Yes, it is normal to investigate the convergence of a series via Laplace transform. The Laplace transform can be used to determine the conditions on the Laplace variable $s$ for which the series converges. This then allows us to determine the conditions on the original variable $t$ for which the series converges.
