Providence, RI—**Ian Agol** of the University of California, Berkeley, is receiving the 2013 AMS Oswald Veblen Prize in Geometry. The Veblen Prize is given every three years for an outstanding publication in geometry or topology that has appeared in the preceding six years. The prize will be awarded on Thursday, January 10, 2013, at the Joint Mathematics Meetings in San Diego.

Agol is honored for “his many fundamental contributions to hyperbolic geometry, 3-manifold topology, and geometric group theory,” the prize citation says. The citation points in particular to the following papers:

- I. Agol, P. Storm, and W. P. Thurston, “Lower bounds on volumes of hyperbolic Haken 3-manifolds” with an appendix by Nathan Dunfield,
*Journal of the AMS*, 20 (2007), no. 4, 1053-1077; - I. Agol, “Criteria for virtual fibering,”
*Journal of Topology*, 1 (2008), no. 2, 269-284; and - I. Agol, D. Groves, and J. F. Manning, “Residual finiteness, QCERF and fillings of hyperbolic groups,”
*Geometry and Topology*, 13 (2009), no. 2, 1043-1073.

Providence, RI—**Daniel Wise** of McGill University is receiving the 2013 AMS Oswald Veblen Prize in Geometry. The Veblen Prize is given every three years for an outstanding publication in geometry or topology that has appeared in the preceding six years. The prize will be awarded on Thursday, January 10, 2013, at the Joint Mathematics Meetings in San Diego.

Wise is honored for “his deep work establishing subgroup separability (LERF) for a wide class of groups and for introducing and developing with Frederic Haglund the theory of special cube complexes which are of fundamental importance for the topology of three-dimensional manifolds,” the prize citation says. The citation mentions in particular the following papers:

- D. T. Wise, “Subgroup separability of graphs of free groups with cyclic edge groups,”
*Quarterly Journal of Mathematics*, 51 (2000), no. 1, 107-129; - D. T. Wise, “Residual finiteness of negatively curved polygons of finite groups,”
*Inventiones Mathematicae*, 149 (2002), no. 3, 579-617; - F. Haglund and D. T. Wise, “Special cube complexes,”
*Geometric and Functional Analysis*, 17 (2008), no. 5, 1551-1620; and - F. Haglund and D. T. Wise, “A combination theorem for special cube complexes,”
*Annals of Mathematics*, 176 (2012), no. 3, 1427-1482.
