Using Chebyshev polynomials to approximate partial differential equations [PDF]
, 2008 This paper suggests a simple method based on a Chebyshev approximation at Chebyshev nodes to approximate partial differential equations. It consists in determining the value function by using a set of nodes and basis functions.

Canonical Sets of Best L1-Approximation
Journal of Function Spaces and Applications, 2012 In mathematics, the term approximation usually means either interpolation on a point set or approximation with respect to a given distance. There is a concept, which joins the two approaches together, and this is the concept of characterization of the ...

Valuing American Put Options Using Chebyshev Polynomial Approximation [PDF]
, 2005 This paper suggests a simple valuation method based on Chebyshev approximation at Chebyshev nodes to value American put options. It is similar to the approach taken in Sullivan (2000), where the option`s continuation region function is estimated by using

On the parallel solution of parabolic equations [PDF]
, 1989 Parallel algorithms for the solution of linear parabolic problems are proposed. The first of these methods is based on using polynomial approximation to the exponential. It does not require solving any linear systems and is highly parallelizable. The two

Implementing smooth functions of a Hermitian matrix on a quantum computer [PDF]
, 2018 We review existing methods for implementing smooth functions f(A) of a sparse Hermitian matrix A on a quantum computer, and analyse a further combination of these techniques which has some advantages of simplicity and resource consumption in some cases ...

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 ...

Low-rank Linear Fluid-structure Interaction Discretizations [PDF]
, 2020 Fluid-structure interaction models involve parameters that describe the solid and the fluid behavior. In simulations, there often is a need to vary these parameters to examine the behavior of a fluid-structure interaction model for different solids and ...
