In the second section, based on the analyses of observations of three systems: IK Per, IR Cas and BL And, some results are concluded as follows:1 Using the 1.0-meter Cassegrain reflector telescope at Yunnan Observatory, we obtained the first complete CCD light curves of IK Per in V and B band respectively.
The reflected electrons of a loss-cone distribution can drive the electron cyclotron maser instability when a nonlinear density wave travells through the bottom part of the magnetic loop. The maser instability will excite the second harmonic O-mode and X-mode to dominate the solar radio millisecond spike radiation.
In the second example, we obtain a proof of the Chalyh-Veselov conjecture that the Calogero-Moser system with integer parameter is algebraically integrable, using the results of Felder and Varchenko.
A local-global principle is proved by the second named author in the adjacent paper of this volume.
In the second part we apply this method to obtain pseudo-Riemannian homogeneous manifolds with real Killing spinors.
We derive two consequences: the first is a new proof of Lusztig's description of the intersection cohomology of nilpotent orbit closures for GLn, and the second is an analogous description for GL2n/Sp2n.
The second part consists in the normalization of the Burkhardt dual.
