- W4386189237 abstract "This paper uses Müntz orthogonal functions to numerically solve the fractional Bagley–Torvik equation with initial and boundary conditions. Müntz orthogonal functions are defined on the interval <math xmlns=http://www.w3.org/1998/Math/MathML id=M1> <mfenced open=[ close=] separators=|> <mrow> <mn>0</mn> <mo>,</mo> <mn>1</mn> </mrow> </mfenced> </math> and have simple and distinct real roots on this interval. For the function <math xmlns=http://www.w3.org/1998/Math/MathML id=M2> <mi>f</mi> <mo>∈</mo> <msup> <mi>L</mi> <mrow> <mn>2</mn> </mrow> </msup> <mfenced open=( close=) separators=|> <mrow> <mn>0</mn> <mo>,</mo> <mn>1</mn> </mrow> </mfenced> </math> , we obtain the best unique approximation using Müntz orthogonal functions. We obtain the Riemann–Liouville fractional integral operator for Müntz orthogonal functions so that we can reduce the complexity of calculations and increase the speed of solving the problem, which can be seen in the process of running the Maple program. To solve the fractional Bagley–Torvik equation with initial and boundary conditions, we use Müntz orthogonal functions and consider simple and distinct real roots of Müntz orthogonal functions as collocation points. By using the Riemann–Liouville fractional integral operator that we define for the Müntz orthogonal functions, the process of numerically solving the fractional Bagley–Torvik equation that is solved using Müntz orthogonal functions is reduced, and finally, we reach a system of algebraic equations. By solving algebraic equations and obtaining the vector of unknowns, the fractional Bagley–Torvik equation is solved using Müntz orthogonal functions, and the error value of the method can be calculated. The low error value of this numerical solution method shows the high accuracy of this method. With the help of the Müntz functions, we obtain the error bound for the approximation of the function. We have obtained the error bounds for the numerical method using which we solved the fractional Bagley–Torvik equation with initial and boundary conditions. Finally, we have given a numerical example to show the accuracy of the solution of the method presented in this paper. The results of solving this example using Müntz orthogonal functions and comparing the results with other methods that have been used the solve this example show the higher accuracy of the method proposed in this paper." @default.
