Query: Minimal Schemes for Large Neutrino Mixings with Inverted Hierarchy   Existing oscillation data point to nonzero neutrino masses with large
mixings. We analyze the generic features of the neutrino Majorana mass matrix
with inverted hierarchy and construct realistic {\it minimal schemes} for the
neutrino mass matrix that can explain the large (but not maximal) \nu_e -
\nu_mu mixing of MSW-LAM as well as the nearly maximal \nu_mu - \nu_tau mixing
and the small (or negligible) \nu_e --> \nu_tau transition. These minimal
schemes are quite unique and turn out to be extremely predictive. Implications
for neutrinoless double beta decay, tritium beta decay and cosmology are
analyzed.
