Abstract (EN): We investigate three different axial-vector form factors of the nucleon, G(A)(0), G(A)(3), G(A)(8), within the framework of the SU(3) chiral quark-soliton model, emphasizing their strangeness content. We take into account the rotational 1/N-c and linear strange quark (m(s)) contributions using the symmetry-conserving SU(3) quantization and assuming isospin symmetry. The strange axial-vector form factor is also obtained and they all are discussed in the context of the parity-violating scattering of polarized electrons off the nucleon and its relevance to the strange vector form factors.
