We present several continuous embeddings of the critical Besov space . We first establish a Gagliardo-Nirenberg type estimate , for 1 < p ≤ q < ∞, 1 ≤ ν < ρ ≤ ∞ and the weight function with 0 < r < n. Next, we prove the corresponding Trudinger type estimate, and obtain it in terms of the embedding , where the function Φ₀ of the weighted Besov-Orlicz space is a Young function of the exponential type. Another point of interest is to embed into the weighted Besov...
