why does the v parameter in the bessel function
x^2y``+xy`+(x^2-v^2)y=0 have to be real and nonegative?
x^2y``+xy`+(x^2-v^2)y=0 have to be real and nonegative?
Bessel functions are a class of special functions that arise in many areas of mathematics and physics, particularly in problems involving oscillations or waves.
The real parameter in Bessel functions refers to the values of the independent variable that the function is evaluated at, while the parameter for y=0 refers to the specific value of the function when the dependent variable is set to 0.
Bessel functions have many applications in science, including in solving differential equations, analyzing wave phenomena, and describing physical processes such as heat transfer and quantum mechanics.
Bessel functions are closely related to other special functions, such as Legendre functions and hypergeometric functions. They can often be expressed in terms of these other functions or can be used to derive them.
Bessel functions have both theoretical and practical applications. They are used in a wide range of fields, including engineering, physics, and statistics, to model and solve real-world problems.
