Using this approach, we can verify a wide variety of classical summation formulas, with typical examples including the q-binomial theorem, the q-Gauss sum, the 6\u03c85 sum, the Ramanujan 1\u03c81 sum, and Bailey's 6\u03c86 sum. In many cases we can discover the companion identities. This work is inspired by the study of two elegant identities involving partial theta functions due to Andrews and Warnaar from the telescoping viewpoint. The key point lies in the fact that the q-Gosper algorithm is effective to deal with q-hypergeometric terms multiplied by the infinite q-shifted factorials.<\/jats:p>","DOI":"10.1145\/1394042.1394052","type":"journal-article","created":{"date-parts":[[2008,7,29]],"date-time":"2008-07-29T13:22:19Z","timestamp":1217337739000},"page":"19-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The q-WZ method for infinite sums (abstract only)"],"prefix":"10.1145","volume":"42","author":[{"given":"William Y.C.","family":"Chen","sequence":"first","affiliation":[{"name":"Nankai University, Tianjin, Peoples Rep of China"}]},{"given":"Ernest X.W.","family":"Xia","sequence":"additional","affiliation":[{"name":"Nankai University, Tianjin, Peoples Rep of China"}]}],"member":"320","published-online":{"date-parts":[[2008,7,25]]},"container-title":["ACM Communications in Computer Algebra"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1394042.1394052","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T12:45:52Z","timestamp":1750250752000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1394042.1394052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,7,25]]},"references-count":0,"journal-issue":{"issue":"1-2","published-print":{"date-parts":[[2008,7,25]]}},"alternative-id":["10.1145\/1394042.1394052"],"URL":"https:\/\/doi.org\/10.1145\/1394042.1394052","relation":{},"ISSN":["1932-2240"],"issn-type":[{"type":"print","value":"1932-2240"}],"subject":[],"published":{"date-parts":[[2008,7,25]]},"assertion":[{"value":"2008-07-25","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
