new integral transforms for solving a steady heat transfer problem

The new Fourier-like integral transforms П(κ)= κ ∞∫−∞ П(t)e-ikt dt, Π(λ)= 1/λ∞∫−∞ П(t)e-iλt dt, П(γ) 1/γ ∞∫−∞ П(t)e-it/γ dt, П(ς)= ς∞∫−∞ П(t)e-it/ς dt are addressed for the first time. They are used to handle a steady heat transfer equation. The proposed methods are efficient and accurate.
