Since the discovery of neutri oscillations neutri physics has become an interesting field of research in physics. They imply that neutri must have a small mass and that the neutris, coupled to the charged leptons, are mixtures of the mass eigenstates, analogous to the flavor mixing of the quarks. The mixing angles for the quarks are small, but for the leptons two of the mixing angles are large. The masses of the three neutris must be very small, less than 1 eV, but from the oscillation experiments we only kw the mass differences - the absolute masses are still unkwn. Also we do t kw, if the masses of the neutris are Dirac masses, as the masses of the charged leptons and of the quarks, or whether they are Majorana masses.In this volume, an overview of the present state of research in neutri physics is given by well-kwn experimentalists and theorists. The contents - originated from talks and discussions at a recent conference addressing some of the most pressing open questions in neutri physics - range from the oscillation experiments to CP-violation for leptons, to texture zero mass matrices and to the role of neutris in astrophysics and cosmology.
