The matching number ?(G) is the number\n   of edges in a maximum matching. In this paper, for a connected graph G of\n   order n with largest vertex degree ? ? 6 we present two new upper bounds for\n   the energy of a graph: ?(G) ? (n-1)?? and ?(G) ? 2?(G)??. The latter\n   one improves recently obtained bound ?(G) ? {2?(G)?2?e + 1, if ?e is\n   even; ?(G)(? a + 2?a + ?a-2?a), otherwise, where ?e stands for the\n   largest edge degree and a = 2(?e + 1). We also present a short proof of this\n   result and several open problems.<\/jats:p>","DOI":"10.2298\/aadm201227016a","type":"journal-article","created":{"date-parts":[[2021,4,23]],"date-time":"2021-04-23T14:14:30Z","timestamp":1619187270000},"page":"444-459","source":"Crossref","is-referenced-by-count":4,"title":["Upper bounds on the energy of graphs in terms of matching number"],"prefix":"10.2298","volume":"15","author":[{"given":"Saieed","family":"Akbari","sequence":"first","affiliation":[{"name":"Department of Mathematical Sciences, Sharif University of Technology, Tehran, Iran"}]},{"given":"Abdullah","family":"Alazemi","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Kuwait University, Safat, Kuwait"}]},{"given":"Milica","family":"Andjelic","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Kuwait University, Safat, Kuwait"}]}],"member":"1078","container-title":["Applicable Analysis and Discrete Mathematics"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,26]],"date-time":"2023-05-26T12:18:46Z","timestamp":1685103526000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1452-86302100016A"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.2298\/aadm201227016a","relation":{},"ISSN":["1452-8630","2406-100X"],"issn-type":[{"value":"1452-8630","type":"print"},{"value":"2406-100X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021]]}}}
