The Sumudu transform is an integral transform introduced in 1990 by G K Watagala.^[1]^[2]^[3] It is defined over the set of functions ^[4]^[5]^[6]

$A=\{f(t):\ni M,p,q>0,|f(t)|=M\exp(1/u)\}$

where $p\leq u\leq q$ , the Sumudu transform is defined as

$S[f(t)]={\frac {1}{u}}\int _{0}^{\infty }f(t)\exp \left(-{\frac {1}{u}}\right)\,dt.$

Relationship with other transforms

Sumudu transform is 1/u Laplace transform $S[f(t)](u)={\frac {1}{u}}L[f(t)]({\frac {1}{u}})$ And with u² Elzaki transform $S[f(t)](u)=u^{2}E[f(t)](u)$
