We establish the existence and multiplicity of solutions for a Kirchhoff-type problem in $$\mathbb R^4$$ involving a critical and concave–convex nonlinearity. Since in dimension four, the Sobolev critical exponent is $$2^*=4$$ , there is a tie betw

The practice of mixing different classes of crop protection products in tank is common for farmers, with efficience losses by compatibility problems, but a lack of research to better understand them. The aim of this study was to evaluate the initial

The improvement of surface coverage and plant protection products deposition can be obtained by electrifying droplets, which are strongly attracted by plants, including the abaxial part of the leaves. Moreover, air assistance improves droplet penetra

We study the existence and multiplicity of weak solutions for a Kirchhoff–Schrodinger type problem in $$\mathbb R^4$$ involving a critical nonlinearity and a suitable small perturbation. When $$N=4$$ , the Sobolev exponent is $$2^*=4$$ and, as a co

In this paper, we study the following class of nonlinear equations: $$ -\Delta u+V(x) u = \left[|x|^{-\mu}*(Q(x)F(u))\right]Q(x)f(u),\quad x\in\mathbb{R}^2, $$ where $V$ and $Q$ are continuous potentials, which can be unbounded or vanishing at infint

We prove the existence of solution for a class of p(x)-Laplacian equations where the nonlinearity has a critical growth. Here, we consider two cases: the first case involves the situation where the variable exponents are periodic functions. The secon
