A Study of Generalized Covariant Hamilton Systems On Generalized Poisson manifold
Since the basic theoretical framework of generalized Hamilton system is not
perfect and complete, there are often some practical problems that can not be
expressed by generalized Hamilton system. The generalized gradient operator is
defined by the structure function on manifold to improve the basic theoretical
framework of the whole generalized Hamilton system. The generalized structure
Poisson bracket is defined as well on manifolds. The geometric bracket is also
given, and the covariant extension form of the generalized Hamilton system
directly related to the structure function, the generalized covariance, is
further obtained--generalized covariant Hamilton system, It includes thorough
generalized Hamiltonian system and S-dynamic system.Comment: 15 page
On non-Abelian group of generalized covariant Hamilton system
This paper considers the non-abelian Lie algebra of Lie groups, by using the
structure constant to construct some new quantities, the GCHS defined by GSPB
\footnote{GPB:Generalized Poisson bracket; GHS:Generalized Hamilton System,
GCHS:Generalized Covariant Hamilton System\\GSPB:Generalized structural Poisson
bracket\\TGHS: thorough generalized Hamiltonian System} is for the covariant
evolution equation that consists of two parts, TGHS and S dynamics. Meanwhile,
the generalized force field given by the GCHS in terms of the momentum applies
to deduce some results.Comment: 8 page
Geometric quantization rules in QCPB theory
Using the QCPB theory, we can accomplish the compatible combination of the
quantum mechanics and general relativity supported by the G-dynamics. We
further study the generalized quantum harmonic oscillator, such as geometric
creation and annihilation operators, especially, the geometric quantization
rules based on the QCPB theory.Comment: 14 page
Efficient and Equitable Airport Slot Allocation
This paper studies slot allocation at congested airports in Europe. First, I discuss the inefficiencies of the current regulation, introduced as part of the liberalisation process of the air transport market. Then, I consider three marked based methods which are suitable to achieve a more efficient allocation of slots to airlines: congestion pricing, auctions and secondary trading. These methods are examined in terms of their ability to improve efficiency and in terms of their implications on the distribution of slots’ scarcity rents. Special attention is drawn to complementarities between slots. Finally, I propose to auction slots periodically, allowing secondary trading well before the first auction takes place. By selling slots before the first auction incumbents can be partially compensated for the subsequent withdrawal of their slots.
An Empirical Investigation on the Efficiency, Capacity Ownership of Italian Airports
In this paper we study the efficiency of Italian airports applying a DEA model to 34 airports. We find that large airports are more efficient than domestic and regional ones, i.e. small airports have spare capacity since they are more distant from the frontier than large airports. The Tobit regression on the estimated DEA scores shows that efficiency is positively related with the hub premium and with privatisation. Hence we suggest that privatisation incentives to invest in large airports (close to saturation) and development plans to improve the small airports may form the benchmarks of Italian short-run air transportation policy.
