D-Enantiomer amino acids, endogenously synthesized and degraded in mammals, participate in multiple developmental and physiological processes. We characterize both d-aspartate and its degradative enzyme (d-aspartate oxidase) in post-natal mouse retina. d-Aspartate attains a developmental peak of 886 nmol/g dry weight at 1-2 weeks post-natal while(More)
Let M1 and M2 be special Lagrangian submanifolds of a compact Calabi-Yau manifold X that intersect transversely at a single point. We can then think of M1 ∪M2 as a singular special Lagrangian submanifold of X with a single isolated singularity. We investigate when we can regularize M1 ∪ M2 in the following sense: There exists a family of Calabi-Yau(More)
The Positive Mass Conjecture states that any complete asymptotically flat manifold of nonnnegative scalar curvature has nonnegative mass. Moreover, the equality case of the Positive Mass Conjecture states that in the above situation, if the mass is zero, then the Riemannian manifold must be Euclidean space. The Positive Mass Conjecture was proved by R.(More)
THE PROGRAM The Ph.D. Program in Mathematics provides students of high ability and strong preparation with an opportunity to begin study for the doctoral degree either immediately upon graduation from college or after completing some graduate work in the colleges of the City University or at other accredited institutions. Doctoral work in mathematics is(More)
