A Gluing Construction Regarding Point Particles in General Relativity

Iva just had her first "solo" paper in the field of general relativity appear. The paper is called: "A Gluing Construction Regarding Point Particles in General Relativity". Here is the abstract:

We develop a gluing construction which adds scaled and truncated asymptotically Euclidean solutions of the Einstein constraint equations to compact solutions with potentially non-trivial cosmological constants. The result is a one-parameter family of initial data which has ordinary and scaled “point-particle” limits analogous to those of Gralla and Wald (Class Quantum Grav 25:205009, 2008). In particular, we produce examples of initial data which generalize Schwarzschild–de Sitter initial data and gluing theorems of IMP-type (Isenberg et al. in Comm Math Phys 231:529–568).

The paper will appear in the journal Annales Henri Poincare, and is already available online (full text is by subscription only). For a pre-print, see the arXiv (free).
