The integer nj depends on the group representation j, and the theory is ill-defined if nj is an odd integer. Witten showed, invoking an Atiyah-Singer index theorem [2] for a certain five-dimensional Dirac operator (the fifth coordinate is essentially the path parameter t), that nj is odd only for the representations in (1). Besides the fundamental representation with j = 1/2, the representation...
The knowledge of the total yield of X-ray radiation is essential for evaluation of a feature of produced plasma and for characterization of different X-ray sources constructed on the basis of plasma facilities. There are some difficulties encountered when dealing with measurements of high fluxes of X-rays from such great plasma facilities as a 1 kJ laser system PALS (Prague Asterix Laser System...
In this paper, we introduce and study a generalized Yosida approximation operator associated to H(·, ·)-co-accretive operator and discuss some of its properties. Using the concept of graph convergence and resolvent operator, we establish the convergence for generalized Yosida approximation operator. Also, we show an equivalence between graph convergence for H(·, ·)-co-accretive operator and gen...
For Schrödinger operators on an interval with either convex or symmetric single-well potentials and Robin Neumann boundary conditions, the gap between two lowest eigenvalues is minimized when potential constant. We also have results for p <mml:annota...
