Gravitational lensing statistics with extragalactic surveys. III. Joint constraints on lambda_0 and Omega_0 from lensing statistics and the m-z relation for type Ia supernovae

Phillip Helbig

I present constraints on cosmological parameters in the lambda_0-Omega_0 plane from a joint analysis of gravitational lensing statistics (astro-ph/9904175) and the magnitude-redshi…
