摘要

本文基于第二类Chebyshev小波和Bernstein方法，研究了一类Dirac算子的逆节点问题，得到了其近似解及其收敛性。我们用部分节点代替密集节点集建立了该问题的唯一性定理。数值算例说明了本文的方法。欲了解更多信息，请参阅https://ejde.math.txstate.edu/Volumes/2023/81/abstr.html

Inverse nodal problems for Dirac operators and their numerical approximations

In this article, we consider an inverse nodal problem of Dirac operators and obtain approximate solution and its convergence based on the second kind Chebyshev wavelet and Bernstein methods. We establish a uniqueness theorem of this problem from parts of nodal points instead of a dense nodal set. Numerical examples are carried out to illustrate our method.
