We have studied the energy distribution curves for a statistically significant number of classical T Tauri stars. It is shown that out of 49 stars, only 7 (14%) has I type of spectrum distribution, the rest belong to type II. Fundamental parameters,

By using the archive photometric data’s obtained for a long time intervals we have carried out a master light curves of 28 classical T Tauri type stars. For the physical character of variability mainly 5 type light curves can be separated. We have

We prove that the class of algebras embeddable into Leibniz algebras with respect to the commutator product is not a variety. It is shown that every commutative metabelain algebra is embeddable into Leibniz algebras with respect to the anti-commutato
