Abstract:This article deals with the study of the following Kirchhoff equation with exponential nonlinearity of Choquard type (see (KC) below). We use the variational method in the light of Moser-Trudinger inequality to show the existence of weak solutions to (KC). Moreover, analyzing the fibering maps and minimizing the energy functional over suitable subsets of the Nehari manifold, we prove existence and multiplicity of weak solutions to convex-concave problem (P λ,M ) below.
“…Now J λ,M (t 1 (u λ )u λ ) < J λ,M (u λ ) ≤ θ which yields a contradiction, since t 1 (u λ )u λ ∈ N λ,M . The proof for u λ being a local minimum for J λ,M in W m,2 0 (Ω) follows exactly as the proof of Theorem 4.12 in [5].…”

“…implies that v k ≤ C. Thus we get S(v k ) * ≤ C 1 and from (3.4) we have ξ − k (0) * ≤ C 2 . Now the rest of the proof follows as in the proof of Theorem 3.9 with the help of Lemma 3.7 (refer Theorem 4.13 of [5]).…”
In this work, we study the higher order Kirchhoff type Choquard equation (KC) involving a critical exponential non-linearity and singular weights. We prove the existence of solution to (KC) using Mountain pass Lemma in light of Moser-Trudinger and singular Adams-Moser inequalities. In the second part of the paper, using the Nehari manifold technique and minimization over its suitable subsets, we prove the existence of at least two solutions to the Kirchhoff type Choquard equation (P λ,M ) involving convex-concave type non-linearity. t 0 M (s) ds is the primitive of the function M vanishing at 0.

The main aim of this article is to study non-singular version of Moser-Trudinger and Adams-Moser-Trudinger inequalities and the singular version of Moser-Trudinger equality in the Cartesian product of Sobolev spaces. As an application of these inequalities, we study a system of Kirchhoff equations with exponential non-linearity of Choquard type.In this connection, in 1960's, Pohozaev [24] and Trudinger [26] independently answered the question using the above function with φ(t) = exp(|t| n n−1 ) − 1. Later on,in [20], Moser improved the result by proving the following inequality which is popularly known as the Moser-Trudinger inequality:MT Theorem 1.1. For n ≥ 2, Ω ⊂ R n is a bounded domain and u ∈ W 1,n 0 (Ω),If κ > κ α,n,m then the above supremum is infinite (i.e. κ α,n,m is sharp).
We study the existence of positive weak solutions for the following problem:
where is a bounded domain in with smooth boundary, is a bounded measurable function on , is nonnegative real number, is the unit outer normal to , , and . The functions and have critical exponential growth, while and are their primitives. The proofs combine the constrained minimization method with energy methods and topological tools.
