The Poincaré-Bertrand formula takes an important position in the study of complex singular integral.The Poincaré-Bertrand formula on the complex spher
In this article,some necessary and sufficient conditions are shown in order that the inequality of the form Φ1(λ)Pu(f> λ) ≤ Ev(Φ2(C|f∞|)) holds with some
In this article,we consider the controllability of a quasi-linear heat equation involving gradient terms with Dirichlet boundary conditions in a bounded domain
