We investigate the following singular quasilinear elliptic system, −Δpu−Δqv=1ua1vb1 in Ω;u|∂Ω=1va2ub2 in Ω;v|∂Ω=0,u>0 in Ω,=0,v>0 in Ω,⎫⎭⎬⎪⎪ where Ω is an open bounded domain with smooth boundary, 1<p,q<∞, and the numbers a1,a2,b1,b2>0 satisfy certain upper bounds. We employ monotonicity methods in order to prove the existence and uniqueness of a pair of positive solutions to (P). While following a standard fixed point approach with ordered pairs of sub- and super solutions, we need to prove a new regularity result of independent interest for solution pairs to problem (P) in C0,β(Ω⎯⎯⎯⎯⎯) with some β∈(0,1).
