The solutions are parameterized by a submanifold of $3\times 3$-matrices (the so-called generating matrices). We show that the constructed solutions are either space-like or of mixed type with the light-cone type isolated singularities.An full version in English of "Doubly periodic maximal surfaces with singularities" (in Russian).
