On Uniqueness of Characteristic Classes
نویسنده
چکیده
We give tools to compare different maps from algebraic K-theory. The results apply in particular to group morphisms from K-theory to any suitable cohomology theory or to K-theory. In particular, we obtain a characterization of the Chern character and of the Adams operations on higher K-theory.

Uniqueness of meromorphic functions dealing with multiple values in an angular domain
This paper uses the Tsuji’s characteristic to investigate the uniqueness of transcen- dental meromorphic function with shared values in an angular domain dealing with the multiple values which improve a result of J. Zheng.
متن کاملRelative Bott-Chern Secondary Characteristic Classes
In this paper, we introduce six axioms for relative Bott-Chern secondary characteristic classes and prove the uniqueness and existence theorem for them. Such a work provides us a natural way to understand and hence to prove the arithmetic Grothendieck-Riemann-Roch theorem.
متن کاملUniqueness in Random-Proposer Multilateral Bargaining
Solution uniqueness is an important property for a bargaining model. Rubinstein’s (1982) seminal 2-person alternating-offer bargaining game has a unique Subgame Perfect Equilibrium outcome. Is it possible to obtain uniqueness results in the much enlarged setting of multilateral bargaining with a characteristic function? In an exploratory effort, this paper investigates a model first proposed in...
متن کاملLagrangian spheres, symplectic surfaces and the symplectic mapping class group
Given a Lagrangian sphere in a symplectic 4-manifold (M,ω) with b+ = 1, we find embedded symplectic surfaces intersecting it minimally. When the Kodaira dimension κ of (M,ω) is −∞, this minimal intersection property turns out to be very powerful for both the uniqueness and existence problems of Lagrangian spheres. On the uniqueness side, for a symplectic rational manifold and any class which is...
متن کاملOn inverse problem for singular Sturm-Liouville operator with discontinuity conditions
In this study, properties of spectral characteristic are investigated for singular Sturm-Liouville operators in the case where an eigen parameter not only appears in the differential equation but is also linearly contained in the jump conditions. Also Weyl function for considering operator has been defined and the theorems which related to uniqueness of solution of inverse proble...
