We compute the isovectors for the Black-Scholes equations by a method
broadly similar to the one used for the heat equation (resp. the heat
equation with potential term) in joint papers with J.-C. Zambrini (see
Progress in Probability vols 58 and 59). It turns out that this computation
suggests Black and Scholes' original solution method for their equation; in
particular, the quantities $r-\frac{{\sigma}^{2}}{2}$ and
$r+\frac{{\sigma}^{2}}{2}$ appear naturally in this context.
