Necessary optimality conditions for delta-nabla isoperimetric problems are proved, and previous results in the literature are obtained as particular cases. As an application of the results of the paper we give necessary and sufficient Pareto optimality conditions for delta-nabla bi-objective optimal control problems.<\/jats:p>","DOI":"10.1177\/1077546310381271","type":"journal-article","created":{"date-parts":[[2010,11,22]],"date-time":"2010-11-22T21:21:50Z","timestamp":1290460910000},"page":"1634-1643","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Delta-nabla optimal control problems"],"prefix":"10.1177","volume":"17","author":[{"given":"Ewa","family":"Girejko","sequence":"first","affiliation":[{"name":"Faculty of Computer Science, Bia\u0142ystok University of Technology, Poland"}]},{"given":"Agnieszka B","family":"Malinowska","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science, Bia\u0142ystok University of Technology, Poland"}]},{"given":"Delfim FM","family":"Torres","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Aveiro, Portugal,"}]}],"member":"179","published-online":{"date-parts":[[2010,11,22]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-0427(01)00432-0"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1177\/1077546309103268"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmaa.2009.06.029"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/j.mcm.2005.08.014"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-0427(01)00437-X"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1016\/j.aml.2007.03.013"},{"key":"atypb7","first-page":"37","volume":"53","author":"Aulbach B.","year":"1990","journal-title":"Colloq.
