Gravitational Lensing of Supernova Neutrino Bursts
Supernova neutrino bursts have been observed from extragalactic distances. This note addresses the question of how gravitational lensing could distort the information in the burst.

DETERMINE THE EFFECTIVE PARAMETERS IN GRAVITATIONAL LENSES AND STUDY THE ALTERNATIVE EFFECTS BETWEEN THEM [PDF]
The importance of the gravitational lens in cosmology and astronomy, and a brief historical review for the evolution of the gravitational lenses have been introduced.

Gravitational Lensing of Continuous Gravitational Waves
Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves.

Can Einstein (rings) surf Gravitational Waves?
How does the appearance of a strongly lensed system change if a gravitational wave is produced by the lens? In this work we address this question by considering a supermassive black hole binary at the center of the lens emitting gravitational waves ...

Gravitational lens time delays and gravitational waves [PDF]
Using Fermat's principle, we analyze the effects of very long wavelength gravitational waves upon the images of a gravitationally lensed quasar. We show that the lens equation in the presence of gravity waves is equivalent to that of a lens with different alignment between source, deflector, and observer in the absence of gravity waves.

Semilinear Gravitational Lens Inversion [PDF]
We describe a new method for analyzing gravitational lens images, for the case where the source light distribution is pixelized. The method is suitable for high resolution, high S/N data of a multiply-imaged extended source. For a given mass distribution, we show that the step of inverting the image to obtain the deconvolved pixelized source light ...

Fixed Points Features in N-Point Gravitational Lenses
A set of fixed points in N-point gravitational lenses is studied in the paper. We use complex form of lens mapping to study fixed points. There are some merits of using a complex form over coordinate. In coordinate form gravitational lens is described by

SOME COROLLARY FACTS OF THE N-POINT GRAVITATIONAL LENS EQUATION IN A COMPLEX FORM
In the theory of the N-point gravita- tional lens equation, two groups of problems can be dis- tinguished. These are the so-called primal and inverse problems.
