Cereceda" ], "comment": "8 pages", "categories": [ "math.NT" ], "abstract": "In 2011, W. Lang derived a novel, explicit formula for the sum of powers of integers $S_k(n) = 1^k + 2^k + \\cdots + n^k$ involving simultaneously the Stirling numbers of the first and second kind. In this note, we first recall and then slightly refine Lang's formula for $S_k(n)$. As it turns out, the modified Lang's formula constitutes a special case of a general relationship discovered by Merca between the power sums, the elementary symmetric functions, and the complete homogeneous symmetric functions.", "revisions": [ { "version": "v1", "updated": "2023-01-05T16:34:42.000Z" } ], "analyses": { "keywords": [ "refinement", "slightly refine langs formula", "complete homogeneous symmetric functions", "modified langs formula constitutes", "elementary symmetric functions" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
