15 صفحه اولPositive paths in the linear symplectic group
A positive path in the linear symplectic group Sp(2n) is a smooth path which is everywhere tangent to the positive cone. These paths are generated by negative definite (time-dependent) quadratic Hamiltonian functions on Euclidean space. A special case are autonomous positive paths, which are generated by time-independent Hamiltonians, and which all lie in the set U of diagonalizable matrices wi...
متن کاملa note on the affine subgroup of the symplectic group
we examine the symplectic group $sp_{2m}(q)$ and its correspondingaffine subgroup. we construct the affine subgroup and show that itis a split extension. as an illustration of the above we study theaffine subgroup $2^5{:}sp_4(2)$ of the group $sp_6(2)$.
متن کاملCONCERNING A LINEAR HOMOGENEOUS GROUP IN Cm>q VARIABLES ISOMORPHIC TO THE GENERAL LINEAR HOMOGENEOUS GROUP IN m VARIABLES
1. While the present paper is concerned chiefly with continuous groups, its results may be readily utilized for discontinuous groups.* Indeed, the finite form of the general transformation of the group is known ah initio. Further, the method is applicable to the construction of a linear Cm> q -ary group isomorphic to an arbitrary m-ary linear group. 2. The formula of composition of m-ary linear...
متن کاملSymplectic structures on right-angled Artin groups: Between the mapping class group and the symplectic group
We define a family of groups that include the mapping class group of a genus g surface with one boundary component and the integral symplectic group Sp.2g;Z/ . We then prove that these groups are finitely generated. These groups, which we call mapping class groups over graphs, are indexed over labeled simplicial graphs with 2g vertices. The mapping class group over the graph is defined to be ...
