Non canonicity of {BL}-algebras
A b s t r a c t. In this work we study canoncity of $\mathbf{BL}$-algebras and some of its
subvarieties. We prove that the only subvarieties of \L $\mathbf{\Pi G}$ (see
page 116) that are $\sigma$-canonical and $\pi$-canonical are
the ones generated by finite families of finite algebras.
