Query: Group Classification of a Generalized Black--Scholes--Merton Equation   The complete group classification of a generalization of the
Black-Scholes-Merton model is carried out by making use of the underlying
equivalence and additional equivalence transformations. For each non linear
case obtained through this classification, invariant solutions are given. To
that end, two boundary conditions of financial interest are considered, the
terminal and the barrier option conditions.
