چکیده
Изучается $n$-мерная система уравнений с доминирующими частными производными $n$-го порядка. Признаком, отличающим рассматриваемую систему от других систем производными, является наличие первого слагаемого в уравнениях правой части системы, представляющего собой доминирующую производную, при этом все остальные входящие уравнения системы производные получаются из нее отбрасыванием по крайней мере одного дифференцирования какой-либо независимых переменных. Целью исследования отыскание условий однозначной разрешимости задачи Гурса для рассматриваемой системы. Основная задача редуцируется к системе интегральных уравнений, решение которой существует и единственно выполнении требований непрерывности ядер правых частей этой соответствующих замкнутых параллелепипедах изменения своих Получены условия, которых основная однозначно разрешима. Окончательный результат терминах коэффициентов исходной формулируется виде теоремы.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
