We show that mass transportation methods provide an elementary approach to the study of certain Sobolev-type inequalities. The Euclidean structure of n-dimensional Euclidean space plays no role in our approach. Besides, to complete our work, we mainly consult the paper [3] and [7].548385 bytesapplication/pdfen-US最優運輸蒙日質量傳遞問題最佳常數索伯列夫不等式加里亞爾多-尼倫堡不等式optimal transportMonge mass transport problemsharp constantsSobolev inequalityGagliardo-Nirenberg inequality以最優運輸方法確定某些索伯列夫型不等式中的最佳常數Sharp certain Sobolev-type inequalities via optimal transportthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/249742/1/ntu-101-R99221010-1.pdf
