In this paper we prove higher integrability results for vector fields B,E, (B,E) ∈ L2− (Ω, R) × L2−ε(Ω, R), ε small, such that div B = 0, curl E = 0 satisfying a “reverse” inequality of the type |B| + |E| ≤ ( K + 1 K ) 〈B,E〉+ |F | with K ≥ 1 and F ∈ L(Ω, R), r > 2 − ε. Applications to the theory of quasiconformal mappings and partial differential equations are given. In particular, we prove reg...

This study concerns the existence of positive solution for the following nonlinear system    −div(|x| −ap |∇u| p−2 ∇u) = |x| −(a+1)p+c 1 (α 1 f (v) + β 1 h(u)), x ∈ Ω, −div(|x| −bq |∇v| q−2 ∇v) = |x| −(b+1)q+c 2 (α 2 g(u) + β 2 k(v) lim s→∞ f (Ag(s) 1 q−1) s p−1 = 0 for every A > 0. We discuss the existence of positive solution when f , g,h and k satisfy certain additional conditions. We use...

Bilateral symmetry of flowers is a relevant novelty that has occurred many times throughout the evolution of flowering plants. In Antirrhinum majus, establishment of flower dorso-ventral asymmetry is mainly due to interaction of TCP (CYC and DICH) and MYB (DIV, RAD, and DRIF) transcription factors. In the present study, we characterized 8 DIV-, 4 RAD-, and 2 DRIF-like genes from the transcripto...

Let S div ( n ) $S_{\rm div}(n)$ denote the set of permutations π such that for each 1 ⩽ j $1\leqslant \leqslant n$ either ∣ $j \mid \pi (j)$ or $\pi (j) j$ . These can also be viewed as vertex-disjoint directed cycle covers divisor graph D [ , ] $\mathcal {D}_{[1,n]}$ on vertices v … $v_1, \ldots v_n$ with an edge between i $v_i$ and $v_j$ if $i\mid i$ We improve recent results Pomerance by sh...
