1: 29.12 Definitions
§29.12(i) Elliptic-Function Form
There are eight types of Lamé polynomials, defined as follows: …
2: 29.6 Fourier Series
In addition, if H satisfies (29.6.2), then (29.6.3) applies. … Consequently, Ec ν 2 m ( z , k 2 ) reduces to a Lamé polynomial; compare §§29.12(i) and 29.15(i). …
3: 31.8 Solutions via Quadratures
the Hermite–Darboux method (see Whittaker and Watson (1927, pp. 570–572)) can be applied to construct solutions of (31.2.1) expressed in quadratures, as follows. … Here Ψ g , N ( λ , z ) is a polynomial of degree g in λ and of degree N = m 0 + m 1 + m 2 + m 3 in z , that is a solution of the third-order differential equation satisfied by a product of any two solutions of Heun’s equation. …(This ν is unrelated to the ν in §31.6.) … For m = ( m 0 , 0 , 0 , 0 ) , these solutions reduce to Hermite’s solutions (Whittaker and Watson (1927, §23.7)) of the Lamé equation in its algebraic form. …When λ = - 4 q approaches the ends of the gaps, the solution (31.8.2) becomes the corresponding Heun polynomial. …
4: 29.1 Special Notation
All derivatives are denoted by differentials, not by primes. The main functions treated in this chapter are the eigenvalues a ν 2 m ( k 2 ) , a ν 2 m + 1 ( k 2 ) , b ν 2 m + 1 ( k 2 ) , b ν 2 m + 2 ( k 2 ) , the Lamé functions Ec ν 2 m ( z , k 2 ) , Ec ν 2 m + 1 ( z , k 2 ) , Es ν 2 m + 1 ( z , k 2 ) , Es ν 2 m + 2 ( z , k 2 ) , and the Lamé polynomials uE 2 n m ( z , k 2 ) , sE 2 n + 1 m ( z , k 2 ) , cE 2 n + 1 m ( z , k 2 ) , dE 2 n + 1 m ( z , k 2 ) , scE 2 n + 2 m ( z , k 2 ) , sdE 2 n + 2 m ( z , k 2 ) , cdE 2 n + 2 m ( z , k 2 ) , scdE 2 n + 3 m ( z , k 2 ) . The notation for the eigenvalues and functions is due to Erdélyi et al. (1955, §15.5.1) and that for the polynomials is due to Arscott (1964b, §9.3.2). … The relation to the Lamé functions L c ν ( m ) , L s ν ( m ) of Jansen (1977) is given by …The relation to the Lamé functions Ec ν m , Es ν m of Ince (1940b) is given by …
5: 29.14 Orthogonality
§29.14 Orthogonality
Lamé polynomials are orthogonal in two ways. First, the orthogonality relations (29.3.19) apply; see §29.12(i). …is orthogonal and complete with respect to the inner product … Each of the following seven systems is orthogonal and complete with respect to the inner product (29.14.2): …
