Non-collapsing condition and Sobolev embeddings for Hajłasz-Besov spaces

In this paper we will focus on understanding the relationship between Sobolev embedding theorems for Hajłasz-Besov spaces defined on a doubling metric measure space (Ω,d,μ) and the non-collapsing condition of the measure, i.e. (Formula presented.) We will also obtain embedding results for Hajłasz-Be...

Sumario:In this paper we will focus on understanding the relationship between Sobolev embedding theorems for Hajłasz-Besov spaces defined on a doubling metric measure space (Ω,d,μ) and the non-collapsing condition of the measure, i.e. (Formula presented.) We will also obtain embedding results for Hajłasz-Besov spaces whose modulus of smoothness is generated by a rearrangement invariant quasi-norm.
