Under fulfillment of the Carleman's condition on the boundary of the rectangle region where the equation is set, the solution is constructed in explicit form. The most important result emerges from the study that a solution for the problem in the form of a Mittag-Leffler is found for the first time.eninfo:eu-repo/semantics/closedAccesshalf-order elliptic equationCarleman's conditionMittag-Leffler seriesCauchy-Riemann equationArticle10.1093/jigpal/jzaf0742-s2.0-1050209922066Q233WOS:001604779200001Q2
