I want to understand how advanced mathematics is applied in forex and gold trading markets. Many professional traders use technical analysis, indicators, probability, and risk management strategies, but I would like to know the mathematical concepts...

Let $H$ be a finite-dimensional $C^*$-Hopf algebra (Kac algebra), and let $K \subseteq H$ be a left coideal subalgebra, meaning that $K$ is a unital subalgebra of $H$ satisfying $\Delta(K) \subseteq H \otimes K$. If $K$ is additionally closed under the...

As the title suggests, I am working on a project that involves simulating several separate one‑dimensional Jacobi (Wright–Fisher) diffusion processes of the form$$d\beta_i(t) = \theta_i (\mu_i - \beta_i(t)) dt + \sigma_i \sqrt{\beta_i(t) (\beta_{i,\max...

For $0 <\alpha < \frac{1}{3}$, let $C \subset [-\frac{1}{2}, \frac{1}{2}]$ denote the fat Cantor set, where intervals of length $\alpha^n$ are removed from the middle of each surviving interval at each of countably many stages. We extend $C$...
