On three families of extended tilde geometries
نویسنده
چکیده
Let Γ be an extended tilde geometry of rank n > 2 such that there exists a 1-covering γ : Γ → Φ where Φ is a c.Cn−1-geometry with orders 1, 2, . . . , 2. Suppose that the normalizer in Aut(Γ ) of the deck group of γ acts flag-transitively on Γ . We prove that, under these hypotheses, only three possibilities exist for the universal cover of Γ . c © 2007 Elsevier Ltd. All rights reserved.

The Flag-transitive Tilde and Petersen-type Geometries Are All Known
We announce the classification of two related classes of flag-transitive geometries. There is an infinite family of such geometries, related to the nonsplit extensions 3 n 2 ] 2 ·Sp2n(2), and twelve sporadic examples coming from the simple groups M22, M23, M24, He, Co1, Co2, J4, BM , M and the nonsplit extensions 3 · M22, 323 · Co2, and 34371 · BM .
متن کاملImplementation of D3Q19 Lattice Boltzmann Method with a Curved Wall Boundary Condition for Simulation of Practical Flow Problems
In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...
متن کاملThe Continuity of the Extended Family Structure within Contemporary Single-Family Houses Case Study: Afghan Immigrant Households in Iran
This research is aimed at reviving the positive aspects of extended family households. The impacts of extended family living on housing design are studied in two steps. In the first step, the history and precedents of extended family housing are explored in both traditional and modern societies. Aside from courtyard houses, numerous other models of extended family housing are introduced and it ...
متن کاملMulti-Tilde-Bar Derivatives
Multi-tilde-bar operators allow us to extend regular expressions. The associated extended expressions are compatible with the structure of Glushkov automata and they provide a more succinct representation than standard expressions. The aim of this paper is to examine the derivation of multi-tilde-bar expressions. Two types of computation are investigated: Brzozowski derivation and Antimirov der...
متن کاملOn X ̃-frames and conjugate systems in Banach spaces
The generalization of p-frame in Banach spaces is considered in this paper. The concepts of an $tilde{X}$-frame and a system conjugate to $tilde{X}$-frame were introduced. Analogues of the results on the existence of conjugate system were obtained. The stability of $tilde{X}$-frame having a conjugate system is studied.
