Existence and Mapping Properties of Wave Operator for the Schrödinger Equation with Singular Potential by Vladimir Georgiev and Angel Ivanov

We consider the Schrödinger equation in three dimensional space with small potential in the Lorentz space L3/2,∞ and we prove Strichartz-type estimates for the solution to this equation. Moreover, using the Cook’s method, we prove the existence of the wave operator. In the last section we prove equivalence between the homogeneous Sobolev spaces Ḣs and Ḣs V in the case 0 ≤ s < 3 2 . 1. Definitio...

Previous research has not adequately measured the effectiveness of a state’s promotion of its tourism product. In this research, the authors use an econometric model to measure the impact of the Croatian, Czech, and Slovak states’ attempts to promote their tourism products abroad. The findings show the effectiveness of the state’s attempts to market their products. The dependent variables in th...

The increasing demand for the use of database systems as an integrating factor in CAD/CAM applications has necessitated the development of database systems with appropriate modelling and retrieval capabilities. One essential problem is the treatment of geometric data which has led to the development of spatial databases. Unfortunately, most proposals only deal with simple geometric objects like...
