The Einstein-scalar field constraints on asymptotically Euclidean manifolds
Yvonne Choquet-Bruhat, James Isenberg, Daniel Pollack
We use the conformal method to obtain solutions of the Einstein-scalar field gravitational constraint equations. Handling scalar fields is a bit more challenging than handling matt…
Ricci flow on locally homogeneous closed 4-manifolds
James Isenberg, Martin Jackson, Peng Lu
We discuss the Ricci flow on homogeneous 4-manifolds. After classifying these manifolds, we note that there are families of initial metrics such that we can diagonalize them and th…
A gluing construction for non-vacuum solutions of the Einstein constraint equations
James Isenberg, David Maxwell, Daniel Pollack
We extend the conformal gluing construction of Isenberg-Mazzeo-Pollack [18] by establishing an analogous gluing result for field theories obtained by minimally coupling Einstein's…
Momentum Maps and Classical Relativistic Fields. Part II: Canonical Analysis of Field Theories
Mark J. Gotay, James Isenberg, Jerrold E. Marsden
With the covariant formulation in hand from the first paper of this series (physics/9801019), we begin in this second paper to study the canonical (or ``instantaneous'') formulatio…
Gluing Initial Data Sets for General Relativity
Piotr T. Chrusciel, James Isenberg, Daniel Pollack
We establish an optimal gluing construction for general relativistic initial data sets. The construction is optimal in two distinct ways. First, it applies to generic initial data…
