研究了各向异性Moser-Trudinger不等式的一个包含Ln范数的精确形式.设λ 1(Ω)= infu ∈ W 0 1,n(Ω),u <$0 <$||F(u)||L n(Ω)n/||u|| Ln(Ω)n是n-Finsler-Laplacian的第一特征值。利用blow-up分析,得到了supu ∈ W 0 1,n(Ω),||F(u)||Ln(Ω)= 1 Ω e λ n(1+ α|| u|| L n(Ω)n)1 n− 1| u| n n− 1 dx对任意0≤ α< λ 1(Ω)是有限的,且对任意α≥ λ 1(Ω)上确界是无限的,其中λ n= n n n− 1 κ n 1 n− 1(κ n是单位武尔夫球的体积),函数F是1次正凸齐次函数,其极函数Fo表示Rn上的Finsler度量。此外,对于任意0≤ α< λ 1(Ω),得到了上确界.
The paper is concerned about a sharp form of Anisotropic Moser-Trudinger inequality which involves L n norm. Let λ 1 (Ω)= inf u∈ W 0 1, n (Ω), u≢ 0⁡|| F (∇ u)|| L n (Ω) n/|| u|| L n (Ω) n be the first eigenvalue associated with n-Finsler-Laplacian. Using blow-up analysis, we obtain that sup u∈ W 0 1, n (Ω),|| F (∇ u)|| L n (Ω)= 1⁡∫ Ω e λ n (1+ α|| u|| L n (Ω) n) 1 n− 1| u| n n− 1 d x is finite for any 0≤ α< λ 1 (Ω), and the supremum is infinite for any α≥ λ 1 (Ω), where λ n= n n n− 1 κ n 1 n− 1 (κ n is the volume of the unit wulff ball) and the function F is positive, convex and homogeneous of degree 1, and its polar F o represents a Finsler metric on R n. Furthermore, the supremum is attained for any 0≤ α< λ 1 (Ω).
