Matveev ’ S Complexity via Crystallization Theory : the Orientable Case ∗
Following the notion of GM-complexity introduced in [8], the present paper performs a graph-theoretical approach to (Matveev’s) complexity computation for closed orientable 3-manifolds. In particular, upper bounds for Matveev’s complexity of closed orientable 3-manifolds triangulated by 28 tetrahedra at most (which are encoded by existing crystallization catalogue C28 due to [17]) are proved to...
متن کاملA Visualization of the Isometry Group Action on the Fomenko{Matveev{Weeks Manifold
The smallest known three-dimensional closed orientable hyperbolic manifoldM 1 , which volume is equal to 0:94 : : :, was obtained independently by A. Fomenko and S. Matveev and by J. Weeks. It is known, that the isometry group of the manifold M 1 is isomorphic to the dihedral group ID 6 of order 12. We study the lattice of the action of the isometry group on the manifoldM 1 and obtain all orbif...
متن کامل"Try and fall sick .."-the composer, chemist, and surgeon Aleksandr Borodin.
Although Aleksandr Porfir’evič Borodin is considered one of the outstanding Russian composers of the 19th century, he left only a very small volume of musical work. He is particularly renowned for the world-famous “Polovtsian Dances” from the opera “Prince Igor” and for his membership in “The Mighty Handful”. Also noteworthy, aside from the forementioned opera “Prince Igor”, are his three symph...
متن کاملFeuding rule makers: Aleksandr Mikhailovich Zaitsev (1841-1910) and Vladimir Vasil'evich Markovnikov (1838-1904). A commentary on the origins of Zaitsev's rule.
Two of the most widely known examples of empirical rules for predicting the outcomes of organic reactions are named for the Russian* chemists Aleksandr Mikhailovich Zaitsev (1841-1910) (1) and Vladimir Vasil’evich Markovnikov (18381904) (2). Today most students in organic chemistry are familiar with the empirical rules devised by these two chemists: Zaitsev’s (Saytzeff’s) Rule for predicting th...
متن کاملVirtual Knots and Links
This paper is an introduction to the subject of virtual knot theory, combined with a discussion of some specific new theorems about virtual knots. The new results are as follows: We prove, using a 3-dimensional topology approach that if a connected sum of two virtual knots K1 and K2 is trivial, then so are both K1 and K2. We establish an algorithm, using Haken-Matveev technique, for recognizing...
