Poisson Dirichlet(α, θ)-Bridge Equations and Coagulation-Fragmentation Duality

Abstract: This paper derives distributional properties of a class of exchangeable bridges closely related to the Poisson-Dirichlet (α, θ) family of bridges. As demonstrated in previous works, stochastic equations based on Poisson-Dirichlet (α, θ) processes, play an important role in a variety of applications. Here we focus on their role in obtaining/identifying otherwise difficult distributiona...

θ–instantons in SU(2) Higgs theory

We consider topology changing processes in SU(2)–Higgs theory. In the Standard Model of particle physics they are accompanied by baryon– and lepton–number non–conservation. At fixed energy and multiplicity of initial state, these processes are described by classical θ–instanton solutions. We describe these solutions and calculate the suppression exponents for the probabilities of the topology c...

Can θ / N Dependence for Gluodynamics be Compatible with 2 π Periodicity in θ ?

In a number of field theoretical models the vacuum angle θ enters physics in the combination θ/N , where N stands generically for the number of colors or flavors, in an apparent contradiction with the expected 2π periodicity in θ. We argue that a resolution of this puzzle is related to the existence of a number of different θ dependent sectors in a finite volume formulation, which can not be se...

Development of Fragility and Reliability Curves and Seismic Vulnerability Evaluation of Talehzang Concrete Bridge

Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...
