Abstract :
this article considers a nonlinear inverse problem of the ostrovsky–burgers equation by using noisy data. two bsplines with different levels, the quintic 𝐵-spline and septic 𝐵-spline, are used to study this problem. for both 𝐵-splines, the stability and convergence analysis are calculated, and results show that an excellent estimation of the unknown functions of thenonlinear inverse problem.
