摘 要:利用函数的变指数空间的理论,讨论关于微分形式的加权的变指数空间。介绍一类满足log-Hlder条件的指数函数,通过最大算子在加A_(p(x))权的变指数空间上的有界性,探讨L^(p(x))(Ω,Λ~l,μ)空间上同伦算子T的有界性,建立在W_d^(p(x))(Ω,Λ~l,μ)空间上的关于同伦算子T的加A_(p(x))权的嵌入定理。建立有界凸域DΩ上的关于任意微分形式的L^(p(x))(Ω,Λ~l,μ)范数的Poincaré不等式,在L~φ(μ)—平均域上给出同伦算子T的加A_(p(x))权Poincaré—型估计。The weighted variable exponent spaces of differential forms are researched by using the theory of the variable exponent spaces of functions. A class of exponent functions which satisfy log-Holder condi- tions is introduced. The boundedness of the homotopy operator T on the spaces Lp(x) (Ω,∧l ,μ) is dis- cussed by employing the boundedness of the Apex) -weighted maximal operator on variable exponent spaces, and the Ap(x) -weighted embedding theorem for homotopy operator T on the space Wpd(x) (Ω,∧l ,μ) is established and applied to any differential forms in the space Wpd(x) (Ω,∧l ,μ) . The Poincare inequality with Lp(x) (Ω,∧l ,μ) norm is obtained for any differential forms in any bounded convex domain D C Ω , and Ap(x) -weighted Poincare-type estimate for homotopy operator T in Lφ (μ) -averaging domain is given.
