Geometric singularities and enhanced gauge symmetries

- M. Bershadsky, K. Intriligator, S. Kachru, D. Morrison, V. Sadov, C. Vafa
- Physics
- 29 May 1996

Abstract Using “Tate's algorithm,” we identify loci in the moduli of F-theory compactifications corresponding to enhanced gauge symmetry. We apply this to test the proposed F-theory/heterotic… Expand

Five-dimensional supersymmetric gauge theories and degenerations of Calabi-Yau spaces

- K. Intriligator, D. Morrison, N. Seiberg
- Physics
- 27 February 1997

Abstract We discuss five-dimensional supersymmetric gauge theories. An anomaly renders some theories inconsistent and others consistent only upon including a Wess-Zumino type Chern-Simons term. We… Expand

Compactifications of F-theory on Calabi-Yau threefolds. (I)

- D. Morrison, C. Vafa
- Physics
- 25 March 1996

Abstract We continue our study of compactifications of F-theory on Calabi-Yau threefolds. We gain more insight into F-theory duals of heterotic strings and provide a recipe for building F-theory… Expand

Compactifications of F-Theory on Calabi--Yau Threefolds -- I

- D. Morrison, C. Vafa
- Physics
- 22 February 1996

We study compactifications of F-theory on certain Calabi--Yau threefolds. We find that $N=2$ dualities of type II/heterotic strings in 4 dimensions get promoted to $N=1$ dualities between heterotic… Expand

Orbifold resolution by D-branes

- M. Douglas, B. Greene, D. Morrison
- Physics
- 21 April 1997

Abstract We study topological properties of the D-brane resolution of three-dimensional orbifold singularities, C 3 /Λ , for finite abelian groups Λ. The D-brane vacuum moduli space is shown to fill… Expand

Non-spherical horizons, I

- D. Morrison, M. Plesser
- Physics
- 23 October 1998

We formulate an extension of Maldacena’s AdS/CFT conjectures to the case of branes located at singular points in the ambient transverse space. For singularities which occur at finite distance in the… Expand

Summing the instantons: Quantum cohomology and mirror symmetry in toric varieties

- D. Morrison, M. Plesser
- Physics, Mathematics
- 30 December 1994

Abstract We use the gauged linear sigma model introduced by Witten to calculate instanton expansions for correlation functions in topological sigma models with target space a toric variety V or a… Expand

F-theory and the Mordell-Weil group of elliptically-fibered Calabi-Yau threefolds

- D. Morrison, Daniel S. Park
- Physics
- 13 August 2012

A bstractThe Mordell-Weil group of an elliptically fibered Calabi-Yau threefold X contains information about the abelian sector of the six-dimensional theory obtained by compactifying F-theory on X.… Expand
