In this paper we determine the perfect powers that are sums of three fifth in an arithmetic progression. More precisely, completely solve Diophantine equation(x−d)5+x5+(x+d)5=zn,n≥2, where d,x,z∈Z and d=2a5b with a,b≥0.
In this paper, we establish a blow up criterion for the short time classical solution of the nematic liquid crystal flow, a simplified version of Ericksen-Leslie system modeling the hydrodynamic evolution of nematic liquid crystals, in dimensions two and three. More precisely, 0 < T∗ < +∞ is the maximal time interval iff (i) for n = 3, |ω|+|∇d|2 / ∈ Lt L ∞ x (R × [0, T∗]); and (ii) for n = 2, |...
