Chebyshev matrix product state approach for time evolution [PDF]
, 2015 We present and test a new algorithm for time-evolving quantum many-body systems initially proposed by Holzner et al. [Phys. Rev. B 83, 195115 (2011)]. The approach is based on merging the matrix product state (MPS) formalism with the method of expanding ...

Chebyshev approach to quantum systems coupled to a bath
, 2007 We propose a new concept for the dynamics of a quantum bath, the Chebyshev space, and a new method based on this concept, the Chebyshev space method. The Chebyshev space is an abstract vector space that exactly represents the fermionic or bosonic bath ...

Modified Chebyshev collocation method for delayed predator–prey system [PDF]
Advances in Difference Equations, 2020 AbstractIn this study, the approximate solutions of the predator–prey system with delay have been obtained by using the modified Chebyshev collocation method. The main technique is that this method transforms the original problem into a system of nonlinear algebraic equations. By using the residual function of the operator equations, error differential

Numerical Approximations Using Chebyshev Polynomial Expansions
, 2001 We present numerical solutions for differential equations by expanding the unknown function in terms of Chebyshev polynomials and solving a system of linear equations directly for the values of the function at the extrema (or zeros) of the Chebyshev ...

Convex structures induced by Chebyshev systems
Indagationes Mathematicae, 2017 Recent developments have clarified that some tools of convex geometry are closely related to separation theorems obtained in the field of functional inequalities. This phenomenon has motivated the authors for the investigation of convex structures induced by Chebyshev systems.
