N2 - We prove that for certain Q-universal quasivarieties K, the lattice of K-quasivarieties contains continuum many subquasivarieties with the undecidable quasi-equational theory and for which the finite membership problem is also undecidable. Moreover, we prove that certain Q-universal quasivarieties have continuum many subquasivarieties with no independent quasi-equational basis.

AB - We prove that for certain Q-universal quasivarieties K, the lattice of K-quasivarieties contains continuum many subquasivarieties with the undecidable quasi-equational theory and for which the finite membership problem is also undecidable. Moreover, we prove that certain Q-universal quasivarieties have continuum many subquasivarieties with no independent quasi-equational basis.
