具有任意增长反应的双相问题

Double-phase problems with reaction of arbitrary growth

Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš

摘要:

考虑由两个不同结构的微分算子和驱动的含参非线性非齐次椭圆型方程。相关的能量泛函具有不平衡的增长,我们没有对反应项施加任何全局增长条件,其行为仅在原点附近规定。利用截断和比较技巧以及莫尔斯理论,我们证明了在大扰动情况下该问题有多个解.我们还表明,如果一个对称性条件施加到反应项,那么我们可以产生一个序列的不同的节点的解决方案,越来越小的能量。

英文摘要:

We consider a parametric nonlinear nonhomogeneous elliptic equation, driven by the sum of two differential operators having different structure. The associated energy functional has unbalanced growth and we do not impose any global growth conditions to the reaction term, whose behavior is prescribed only near the origin. Using truncation and comparison techniques and Morse theory, we show that the problem has multiple solutions in the case of high perturbations. We also show that if a symmetry condition is imposed to the reaction term, then we can generate a sequence of distinct nodal solutions with smaller and smaller energies.
