Abstract We discuss the asymptotics of the eigenvalue counting function for partial differential operators and related expressions paying the most attention to the sharp asymptotics. We consider Weyl asymptotics, asymptotics with Weyl principal parts

In this article we consider fractional Laplacians which seem to be of interest to probability theory. This is a rather new class of operators for us but our methods works (with a twist, as usual). Our main goal is to derive a two-term asymptotics as

Under certain assumptions we derive a complete semiclassical asymptotics of the spectral function \(e_{h,\varepsilon }(x, x,\lambda )\) for a scalar operator $$\begin{aligned} A_\varepsilon (x, hD)= A^0(hD) + \varepsilon B(x, hD), \end{aligned}$$ whe

The purpose of this Part is to apply semiclassical methods developed in the previous parts to the theory of heavy atoms and molecules. Because of this we combine our semiclassical methods with the traditional methods of that theory, mainly function-a

This Chapter is a continuation of Chapter 13 and Sections 4.6 and 5.4. Here we deal with the Schrodinger operator with the strong magnetic field in dimensions 2 and 3 under weak smoothness assumptions.

This chapter is devoted to even more specialized results than the previous one. In Section 6.1 we extend some of the above results to conjoint spectral asymptotics for families of commuting operators (general or scalar). Then in Section 6.2 we consid
