Levin–Cochran–Lee inequalities and best constants on homogeneous groups
In this paper, we apply a direct method instead of a limit approach, for proving the Levin–Cochran–Lee inequalities. First, we state and prove Levin–Cochran–Lee type inequalities on a homogeneous group \(\mathbb {G}\) with parameters \(0<p\le q<\infty \). Furthermore, for the case \(p=q\), we prove the sharp inequalities with power weights and derive some other new inequalities.
期刊介绍:
aequationes mathematicae is an international journal of pure and applied mathematics, which emphasizes functional equations, dynamical systems, iteration theory, combinatorics, and geometry. The journal publishes research papers, reports of meetings, and bibliographies. High quality survey articles are an especially welcome feature. In addition, summaries of recent developments and research in the field are published rapidly.
