Abstract: We investigate the strongly singular partial differential equations of matrix-type,

where Ω is a bound and open set in Rn, M(x) is a real symmetric matrix on Ω, -p<-1,0 < q < 1,λ>0 are parameters, f(x)∈L1(Ω),f(x)>0 a.e. in Ω. We prove that the above-mentioned equation admits at least one positive H01-solution when λ>0 if there exists u0H01(Ω) such that ∫Ωf(x)|u0|1-pdx <+∞. It should be noted that a classical solution, namely, the C2(Ω)∩C(Ω)-solution, is not necessarily a H01(Ω)-solution for singular equations.

Key words: H01-solution, real symmetric matrix, strong singularity
