Pointwise multiplicative inequalities and Nirenberg type estimates in weighted Sobolev spaces.(English)Zbl 0819.46021

Summary: We prove pointwise multiplicative inequalities on bounded domains with the cone property and on infinite cones, and derive a certain class of multiplicative inequalities in weighted Sobolev spaces with Muckenhoupt weights. We also find some new formulas to represent functions by their derivatives.
