We consider the optimality of various institutional arrangements for agencies that conduct macro-prudential regulation and monetary policy. When a central bank is in charge of price and financial stability, a new time inconsistency problem may arise. Ex-ante, the central bank chooses the socially optimal level of inflation. Ex-post, however, the central bank chooses inflation above the social o...

We solve the Klein-Gordon equation in the presence of a spatially one-dimensional cusp potential. The bound state solutions are derived and the antiparticle bound state is discussed.

In this paper we discuss a simple and general model for evaluating optimal investment level in information security proposed by Gordon and Loeb [5]. The authors leave an open question, whether there exists some universal upper limit for the level of optimal security investments compared to the total cost of the protected information set. They also conjecture that if such a level exists, it coul...

The purpose of this paper is to develop the negative order MKdV hierarchy and to present a new related integrable Neumann-like Hamiltonian flow from the view point of inverse recursion operator and constraint method. The whole MKdV hierarchy both positive and negative is generated by the kernel elements of Lenard’s operators pair and recursion operator. Through solving a key operator equation, ...

In view of the extensive investigations carried on by Olitsky and Gates'' with reference to the causative agent in epidemic influenza, and particularly in view of the fact that the claims of these observers regarding the demonstration in material and cultures from influenzal patients of a filter-passing microorganism have been more or less confirmed by the reports of Gordon a in England, and Li...

We study the asymptotic behavior in time of the solutions of a system of nonlinear Klein-Gordon equations. We have two basic results: First, in the L@R3) norm, solutions decay like 0(t-3/2) as t/+ provided the initial data are sufficiently small. Finally we prove that finite energy solutions of such a system decay in local energy norm as t++.

We study the deformed kinematics of point particles in the Hořava theory of gravity. This is achieved by considering particles as the optical limit of fields with a generalized Klein-Gordon action. We derive the deformed geodesic equation and study in detail the cases of flat and spherically symmetric (Schwarzschild-like) spacetimes. As the theory is not invariant under local Lorenz transformat...

Ternary stress presents a unique challenge to constraint-based metrical stress theories. The main question is how to model ternarity without ternary-specific representations, such as ternary feet. Along this line of reasoning, Elenbaas and Kager (1999) interpret ternarity as an underparsing effect in which long lapses are avoided while the number of feet is kept to a minimum. The standard const...
