A bstract We propose the full system of Baxter Q-functions (QQ-system) for integrable spin chains with symmetry D r Lie algebra. use this QQ-system to derive new Weyl-type formulas expressing transfer matrices in all symmetric and antisymmetric (fundamental) representations through + 1 basic Q-functions. Our functional relations are consistent Q-operators proposed recently by one authors verifi...

Let p be a positive integer and let Q be a subset of {0, 1, . . . , p}. Call p sets A1, A2, . . . , Ap of a ground set X a (p,Q)-system if the number of sets Ai containing x is in Q for every x ∈ X. In hypergraph terminology, a (p,Q)-system is a hypergraph with p edges such that each vertex x has degree d(x) ∈ Q. A family of sets F with ground set X is called (p,Q)-free if no p sets of F form a...

Author article stakes part in several projects focused just on development of technical creativity and imagination in students of faculties of education, teachers and primary school pupils. The article deals with the teacher’s approach to the teaching of psychomotor skills, while specifically seeking to answer whether among teachers of technical education and practical activities, there are gro...
