Remarks on inflation and noncommutative geometry (2001)
Journal Article
Chu, C., Greene, B., & Shiu, G. (2001). Remarks on inflation and noncommutative geometry. Modern Physics Letters A, 16(34), 2231-2240. https://doi.org/10.1142/s0217732301005680

We briefly discuss some possible cosmological implications of noncommutative geometry. While the noncommutativity we consider does not affect gravity, it can play an important role in the dynamics of other fields that are present in the early univers...

Globally Optimal Regions and Boundaries as Minimum Ratio Cycles (2001)
Journal Article
Jermyn, I., & Ishikawa, H. (2001). Globally Optimal Regions and Boundaries as Minimum Ratio Cycles. IEEE Transactions on Pattern Analysis and Machine Intelligence, 23(10), 1075-1088. https://doi.org/10.1109/34.954599

We describe a new form of energy functional for the modeling and identification of regions in images. The energy is defined on the space of boundaries in the image domain and can incorporate very general combinations of modeling information both from...

On the convergence to stationarity of birth-death processes (2001)
Journal Article
Coolen-Schrijner, P., & Van Doorn, E. (2001). On the convergence to stationarity of birth-death processes. Journal of Applied Probability, 38(3), 696-706. https://doi.org/10.1239/jap/1005091033

Taking up a recent proposal by Stadje and Parthasarathy in the setting of the many-server Poisson queue, we consider the integral ∫0∞[limu→∞E(X(u))-E(X(t))]dt as a measure of the speed of convergence towards stationarity of the process {X(t) , t≥0},...

The enhançon and the consistency of excision. (2001)
Journal Article
Johnson, C. V., Myers, R. C., Peet, A. W., & Ross, S. F. (2001). The enhançon and the consistency of excision. Physical Review D, 64(10), Article 106001. https://doi.org/10.1103/physrevd.64.106001

The enhançon mechanism removes a family of timelike singularities from certain supergravity spacetimes by forming a shell of branes on which the exterior geometry terminates. The problematic interior geometry is replaced by a new spacetime, which in... Read More about The enhançon and the consistency of excision..

Hopf solitons from instanton holonomy. (2001)
Journal Article
Ward, R. (2001). Hopf solitons from instanton holonomy. Nonlinearity, 14(6), 1543-1554. https://doi.org/10.1088/0951-7715/14/6/307

The holonomy of an SU(2) N-instanton in the x4-direction gives a map from Bbb R3 into SU(2), which provides a good model of an N-Skyrmion. Combining this map with the standard Hopf map from SU(2)congS3 to S2 gives a configuration for a Hopf soliton o... Read More about Hopf solitons from instanton holonomy..

Supersymmetric conical defects: towards a string theoretic description of black hole formation (2001)
Journal Article
Balasubramanian, V., de Boer, J., Keski-Vakkuri, E., & Ross, S. F. (2001). Supersymmetric conical defects: towards a string theoretic description of black hole formation. Physical Review D, Particles and fields, 64(6), https://doi.org/10.1103/physrevd.64.064011

Conical defects, or point particles, in AdS3 are one of the simplest nontrivial gravitating systems, and are particularly interesting because black holes can form from their collision. We embed the BPS conical defects of three dimensions into the N=4... Read More about Supersymmetric conical defects: towards a string theoretic description of black hole formation.

The critical dimension of bosonic string theory in AdS space-time. (2001)
Journal Article
Davies, I., & Mansfield, P. The critical dimension of bosonic string theory in AdS space-time. Manuscript submitted for publication

The Polyakov bosonic string is quantised in Euclidean Anti-de Sitter space-time using functional methods. Regularisation of the functional determinants using both heat-kernel and zeta function techniques shows that the AdS_{D+1} string reduces to the...

Test of gauged N = 8 SUGRA/N = 1 SYM duality at sub-leading order (2001)
Journal Article
Mansfield, P., & Nolland, D. (2001). Test of gauged N = 8 SUGRA/N = 1 SYM duality at sub-leading order. Physics Letters B, 515(1-2), 192-196. https://doi.org/10.1016/s0370-2693%2801%2900826-7

An infra-red fixed point of N = 1 super-Yang–Mills theory is believed to be dual to a solution of five-dimensional gauged N = 8 supergravity. We test this conjecture at next to leading order in the large N expansion by computing bulk one-loop correct... Read More about Test of gauged N = 8 SUGRA/N = 1 SYM duality at sub-leading order.

Brane fusion in the bosonic string and the emergence of fermionic strings (2001)
Journal Article
Englert, F., Houart, L., & Taormina, A. (2001). Brane fusion in the bosonic string and the emergence of fermionic strings. Journal of High Energy Physics, 2001(08), https://doi.org/10.1088/1126-6708/2001/08/013

We review the emergence of the ten-dimensional fermionic closed string theories from subspaces of the Hilbert space of the 26-dimensional bosonic closed string theory compactified on an E8 × SO(16) lattice. They arise from a consistent truncation pro... Read More about Brane fusion in the bosonic string and the emergence of fermionic strings.
