Question:
Show that the second derivative with respect to strike of the call payoff f(ST ,K) = (ST − K, 0)+, at expiry T is given by:
where δ(ST −K) denotes the Dirac delta function, satisfying the property;
for a function f of a real variable x. Use this property to show that, for the undiscounted call price
