On the problem of constraints in nonextensive formalism: A quantum mechanical treatment
Bagci, G. B.; Arda, Altug; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2006-06-10)
Relative entropy (divergence) of Bregman type recently proposed by T. D. Frank and Jan Naudts is considered and its quantum counterpart is used to calculate purity of the Werner state in nonextensive formalism. It has been observed that two different expressions arise due to two different forms of quantum divergences. It is then argued that the difference is due to the fact that the relative entropy of Bregman type is related to the first choice thermostatistics whereas one of Csiszar type is related to the...

On the algebraic structure of relative hamiltonian diffeomorphism group
Demir, Ali Sait; Ozan, Yıldıray; Department of Mathematics (2008)
Let M be smooth symplectic closed manifold and L a closed Lagrangian submanifold of M. It was shown by Ozan that Ham(M,L): the relative Hamiltonian diffeomorphisms on M fixing the Lagrangian submanifold L setwise is a subgroup which is equal to the kernel of the restriction of the flux homomorphism to the universal cover of the identity component of the relative symplectomorphisms. In this thesis we show that Ham(M,L) is a non-simple perfect group, by adopting a technique due to Thurston, Herman, and Banyag...
On the discretization of Darboux Integrable Systems
Zheltukhın, Kostyantyn (Informa UK Limited, 2020-10-01)
We study the discretization of Darboux integrable systems. The discretization is done using x-, y-integrals of the considered continuous systems. New examples of semi-discrete Darboux integrable systems are obtained.
On the balanced k-chinese postmen problems
Limon, Yasemin; Azizoğlu, Meral; Department of Industrial Engineering (2015)
In this thesis, we consider a k-Chinese Postmen Problem with the objective of minimizing total squared workloads. Our aim is to balance the workloads of the postmen, while maintaining low total workload. We develop an efficient subtour elimination constraint and incorporate it to our integer program. We develop exact and approximate solution procedures that run in exponential and polynomial time respectively. The results of our computational experiment reveal the satisfactory behaviors of our algorithms in ...
