Abstract:
An inversion algorithm is derived for the dual Weierstrass-Laguerre transform $\int _0^\infty {{g_\alpha }(x,y;1)\varphi (y){y^\alpha }{e^{ - y}}/(\alpha + 1)dy}$, where the function ${g_\alpha }(x,y,t)$ is associated with the source solution of the Laguerre differential heat equation $x{u_{xx}}(x,t) = (\alpha + 1 - x){u_x}(x,t) = {u_t}(x,t)$. Correspondingly, sufficient conditions are established for a function to be represented by a Weierstrass-Laguerre Stieltjes transform $\int _0^\infty {{g_\alpha }(x,y;1)\;d\beta (y)}$ of a nondecreasing function $\beta$.References
