This, in particular, provides for a further description of the Cadoni correspondence (which extends the Gegenberg-Kunstatter correspondence) of soliton solutions and extremal black hole solutions in 2D dilaton gravity.Submitted to Phys Rev D, 7 pages, no figuresHigh Energy Physics - TheoryMathematical Physicstext
