Аннотация
We consider the XY Heisenberg spin \( \frac{1}{2} \) chain in the fermion representation. The construction of the ground-state vector is based on the group-theoretical approach. An exact expression for the ground-state vector will allow one to study the combinatorics of the correlation functions of the model.
