| Popis: | We construct the deformation quantization with separation of variables on the Grassmannian $G_{2,4}\left(\mathbb{C}\right)$. The star product on $G_{2,4}\left(\mathbb{C}\right)$ can be explicitly determined as the solution of the recurrence relations for $G_{2,4}\left(\mathbb{C}\right)$ given by Hara and one of the authors (A. S.). To give the solution of the recurrence relations, it is necessary to solve a system of linear equations at each order. However, to give the concrete expression of the general term is not easy because the variables increase with the order of the differentiation of the star product. For this reason, there has been no formula to express the general term of the recurrence relations. In this paper, by overcoming this problem by transforming the recurrence relations into simpler ones, we obtain the formula for the general term. We solve the recurrence relations by using creation and annihilation operators on a Fock space. From this solution, we obtain the explicit formula of the star product with separation of variables on $G_{2,4}\left(\mathbb{C}\right)$.
