DEVELOPMENT OF 3D MODELING OF THORACOSCOPIC OPERATIONS ON LUNGS

According to official statistics in Russia, hundreds of thousands of cases of tuberculosis and lung cancer are reported each year. Computed tomography (CT) is the first examination for such patients. Next, to clarify the diagnosis, histology of a sample of pathological tissue is performed

Subword complexes, cluster complexes, and generalized multi-associahedra

In this paper, we use subword complexes to provide a uniform approach to finite type cluster complexes and multi-associahedra. We introduce, for any finite Coxeter group and any nonnegative integer k, a spherical subword complex called multi-cluster complex. For k=1, we show that this subword complex is isomorphic to the cluster complex of the given type. We show that multi-cluster complexes of types A and B coincide with known simplicial complexes, namely with the simplicial complexes of multi-triangulations and centrally symmetric multi-triangulations respectively. Furthermore, we show that the multi-cluster complex is universal in the sense that every spherical subword complex can be realized as a link of a face of the multi-cluster complex.Comment: 26 pages, 3 Tables, 2 Figures; final versio
