Bessel polynomials satisfy a specific condition, called Bessel orthogonality. The weight with respect to which Bessel polynomials are orthogonal is a hyperfunction with a point mass. We solve the problem (raised by E. Grosswald) of finding other set of functions that have this property.
Bessel 다항식들의 Weight는 Bessel 직교성이라는 특별한 성질을 갖는다. Bessel 다항식과 같은 성질을 갖는 해석함수족을 찾았다.
