Change of the stock price dynamics while pricing using the Fourier transform techniques
Right now I am trying to understand how we can use the Fourier theorem in obtaining the formula for option pricing (from Zhu J., "Modular pricing of options").
While modeling the interest ...

Zero-rebate barrier option pricing under the Heston model
I'm trying to derive an approximation for the zero-rebate barrier option under the Heston model:
$$dS_t=\mu S_tdt+\sqrt{v_t}S_tdW^S_t$$
$$dv_t=\kappa(\bar{v}-v_t)dt+\eta\sqrt{v_t}dW^v_t,\quad d\langle ...

Fourier transform of price function
If the expiry value is given by $f(x,T) = e^{-c x}$ for $x \ge a$ and 0 otherwise and c is a +ve constant, prove that in the Fourier domain:
$$
(c + j \omega) F(\omega, 0) = e^{-rT} e^{-a(c+j\omega)}...

Fourier transform Carr-Madan method on an arbitrar initial $S_0$ values
As mentioned in Carr-Madan's paper, here, the European call option is:
$$
C_T(k)=\frac{e^{\alpha k}}{\pi}\int_0^\infty\mathcal{Re}\left(e^{-iuk}\psi(u)\right)du
$$
where
$$
\psi(u)=e^{-rT}\frac{\phi_T(...
