This function returns the values: where the points (a, b, c) consist of all triples formed by taking a from x, b from y, and c from z. The resulting points form a grid with x in the first dimension, y in the ... Webb6 okt. 2024 · Hence. ∇ † = − ∇ (∇ †)m = ( − 1)m∇m. To demonstrate orthogonality of the associated Legendre polynomials, we use a result from the theory of orthogonal polynomials. Namely, a Legendre polynomial of order l is orthogonal to any polynomial Πp of order p lower than l . In bra-ket notation: Πp Pl = 0 if O(Πp) ≡ p < l.

WebbIn mathematics, the associated Legendre functions are the canonical solutions of the general Legendre equation. or. where the indices and m (which in general are complex quantities) are referred to as the degree and order of the associated Legendre function respectively. This equation has solutions that are nonsingular on [−1, 1] only if and ... WebbOur work is based on the multiple inequalities illustrated in 2024 by Hamiaz and Abuelela. With the help of a Fenchel-Legendre transform, which is used in various problems involving symmetry, we generalize a number of those inequalities to a general time scale. Besides that, in order to get new results as special cases, we will extend our results to …
