A class function on the mapping class group of an orientable surface and the Meyer cocycle
Meyer [9] defined a cocycle g 2Z.MgIZ/ (g 0) called the Meyer cocycle which represents four times generator of the second cohomology class when g 3. Let D1 , D2 , and D3 be mutually disjoint disks in S , and Int Di the interior of Di for i D 1; 2; 3. We denote by P WDS q iD1 Int Di the pair of pants, and ̨; ˇ; 2 1.P / be the homotopy classes as shown in Figure 1. We consider a †g;r –bundle E '; ...
متن کاملMod 2 Homology of the Stable Spin Mapping Class Group
We compute the mod 2 homology of spin mapping class groups in the stable range. In earlier work [G] we computed the stable mod p homology of the oriented mapping class group, and the methods and results here are very similar. The forgetful map from the spin mapping class group to the oriented mapping class groups induces a homology isomorphism for odd p but for p = 2 it is far from being an iso...
متن کاملThe Torelli group and congruence subgroups of the mapping class group
Let Σg,n be a compact oriented genus g surface with n boundary components. The mapping class group of Σg,n, denoted Modg,n, is the group of orientation-preserving diffeomorphisms of Σg,n that restrict to the identity on ∂Σg,n, modulo isotopies that fix ∂Σg,n. The group Modg,n plays a fundamental role in many areas of mathematics, ranging from low-dimensional topology to algebraic geometry. At l...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Homology cylinders: an enlargement of the mapping class group
We consider a homological enlargement of the mapping class group, defined by homology cylinders over a closed oriented surface (up to homology cobordism). These are important model objects in the recent Goussarov-Habiro theory of finite-type invariants of 3-manifolds. We study the structure of this group from several directions: the relative weight filtration of Dennis Johnson, the finite-type ...
