RSA cryptography, which is one of the typical public key cryptosystems, is a cryptosystem based on the fact that it is difficult to factor a composite number with a large number of digits into prime ...

This paper shows how the recently developed fractional FFT algorithm (FRFT) can be used to retrieve option prices from the corresponding characteristic functions. The FRFT algorithm has the advantage ...

You probably have at least a nodding familiarity with the Fourier transform, a mathematical process for transforming a time-domain signal into a frequency domain signal. In particular, for computers, ...

Fear Factor (2001) Season 3 continued the reality TV show’s format of pushing contestants to their limits with extreme and fear-inducing challenges. Hosted by Joe Rogan, the season featured a variety ...

Prime numbers are all the rage these days. I can tell something’s up when random people start asking me about the randomness of primes—without even knowing that I’m a mathematician! In the past couple ...
