It is shown that a change of variable in 1-dim Schrödinger equation applied to the Borel summable fundamental solutions [8, 9] is equivalent to Borel resummation of the fundamental solutions multiplied by suitably chosen ¯ h-dependent constant. This explains why change of variable can improve JWKB formulae [11]. It is shown also that a change of variable(More)
