Existence of solutions for solitons type equations in several space dimensions: Derrick's Problem with $(r,p)$-Laplacian


Abstract

In this paper we study a class of Lorentz invariant nonlinear field equations in several space dimensions. The main purpose is to obtain soliton-like solutions with twice $(r,p)$-Laplacian. The fields are characterized by a topological invariant, which we call the charge. We prove the existence of a static solution which minimizes the energy among the configurations with nontrivial charge.

У статті вивчається клас нелінійних рівнянь, інваріантних відносно лоренцевих перетворень, для поля з декількома просторовими зміними. Основною метою є отримання солітоноподібних розв'язків з подвійним $(r,p)$-лапласіаном. Поля характеризуються топологічним інваріантом, який ми називаємо зарядом. Доведено існування статичного розв'язку, який мінімізує енергію в конфігураціях з нетривіальним зарядом.

Key words: Soliton, variational calculus, splitting lemma.
