Complete homogeneous symmetric functions
Due to the connection with representation theory, a symmetric function which expands positively in Schur functions are of particular interest. For example, the skew Schur functions expand positively in the ordinary Schur functions, and the coefficients are Littlewood–Richardson coefficients. A special case of this is the expansion of the complete homogeneous symmetric functions hλ in … http://sporadic.stanford.edu/reference/combinat/sage/combinat/sf/homogeneous.html

The complete homogeneous symmetric polynomial of degree k in n variables X1, ..., Xn, written hk for k = 0, 1, 2, ..., is the sum of all monomials of total degree k in the variables. Formally, $${\displaystyle h_{k}(X_{1},X_{2},\dots ,X_{n})=\sum _{1\leq i_{1}\leq i_{2}\leq \cdots \leq i_{k}\leq n}X_{i_{1}}X_{i_{2}}\cdots … See more In mathematics, specifically in algebraic combinatorics and commutative algebra, the complete homogeneous symmetric polynomials are a specific kind of symmetric polynomials.
