The mathematics of symmetry, also known as group theory, is widely used as a tool in the solution of complex problems in many areas of theoretical physics, including string theory. A sequence of ...

We present two fast algorithms for finding the solution of the nonsingular lower Hessenberg quasi-Toeplitz linear system stem from Markov chain. And we confirm the complexity of these two algorithms ...

Distinguishing between various possibilities is fundamental to the scientific method and the process of discovery and categorization. As such, mathematical methods underlying distinguishability have ...
