Existence of ground states for approximately inner two--parameter $C_0$--groups on $C^*$--algebras
In this paper, we generalize the definitions of approximately inner $C_0$-groups and their ground states to the two- parameter case and study necessary and sufficient conditions for a state to be ground state. Also we prove that any approximately inner two- parameter $C_0$--group must have at least one ground state. Finally some applications are given.
متن کاملA Self-Consistent Technique for the Construction and Evaluation of the Three-Parameter Corresponding States Principles
A self-consistent approach for the evaluation of the existing three-parameter corresponding states principles of non-polar fluids and the calculation of the corresponding states parameters is presented. This self consistent approach is based upon the assumption that the contribution of the third parameter to the thermophysical properties is much smaller than the contributions of the first two p...
متن کاملInner Automorphisms of Right-angled Coxeter Groups
If W is a right-angled Coxeter group, then the group Aut(W ) of automorphisms of W acts on the set of conjugacy classes of involutions in W. Following Tits [16], the kernel of this action is denoted by Aut◦(W ). Since W is a CAT(0) group [12], the index of Aut◦(W ) in Aut(W ) is finite and there is a series 1 Inn(W ) Aut◦(W ) Aut(W ) of normal subgroups of Aut(W ). A presentation for Aut◦(W ) w...
متن کاملn-INNER AUTOMORPHISMS OF FINITE GROUPS
We refer to an automorphism g of a group G as n-inner if given any subset S of G with cardinality less than n, there exists an inner automorphism of G agreeing with g on S. Hence g is 2-inner if it sends every element of G to a conjugate. New examples are given of outer n-inner automorphisms of finite groups for all natural numbers n ≥ 2.
متن کاملAutomorphisms of One-relator Groups
It is a well-known fact that every group G has a presentation of the form G = F/R, where F is a free group and R the kernel of the natural epimorphism from F onto G. Driven by the desire to obtain a similar presentation of the group of automorphisms Aut(G), we can consider the subgroup Stab(R) ⊆ Aut(F ) of those automorphisms of F that stabilize R, and try to figure out if the natural homomorph...
