We consider a lattice generated by three elements, one of which is completely modular. The free lattice with this property is proved to be finite. It is not modular and contains exactly 39 elements. We have also found a finite set of defining relations for the generating elements of this lattice. 相似文献

We consider the 3-generated lattices whose generators enjoy the defining relations of the type a∨(b∧c) = (a∨b)∧(a∨c). Moreover, if the lattice is finite then we obtain its diagram; otherwise, we prove that the corresponding lattice is infinite. 相似文献

We consider a lattice generated by three elements, two of which are semi-normal. We have proved it is infinite and have also found an additional condition for the lattice to be modular. As a result, it is proved that the sublattice generated in the subgroup lattice by two normal subgroups and any subgroup is modular. 相似文献

The radiation-measurement complex associated with the Sirius synchrotron has been operating in the Scientific-Research Institute of Nuclear Physics of the S. M. Kirov Polytechnic Institute in Tomsk since 1985. Research on meson physics, channeling of high-energy electrons in crystals, new types of radiation, and applications of synchrotron radiation is carried out in this complex. The renovation of the synchrotron presently under way will allow these problems to be studied more effectively.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 5–7, June, 1991. 相似文献
