The proposed research involves research in Theoretical Physics but primarily in String Theory. We plan to explore the dynamics of the gauge/string dualities. We are planning to investigate a new formulation of spinning strings, which uses a W-algebra. We are also going to investigate whether the cosmological constant can be understood by dynamical screening due to infrared effects. We are planning to work on relations between string theory and gauge theory. We will study the interaction of strings via the light cone string field theory. We are interested in constructing a string bit theory, which interpolates between gauge theory and string theory. We will study warped compactifications of string theory with internal fluxes in order to understand field theories with Supersymmetry breaking. We will study non-commutativity in string theory and its connection with non-commutative geometry. Special interest will be paid to how these theories will affect the cosmic microwave background. We will also study the quantum physics of black holes. We will focus our attention on three dimensional gauge theories especially with an interest of understanding strong-weak coupling dualities. We also will study large-N membrane theories.

拟议的研究涉及理论物理学的研究，但主要用于弦理论。我们计划探索规格/字符串二元性的动态。 我们计划研究使用W-代数的新型旋转字符串。我们还将研究是否可以通过红外效应引起的动力筛选来理解宇宙常数。我们计划在弦理论与量规理论之间进行关系。 我们将通过轻锥字符串场理论研究字符串的相互作用。我们有兴趣构建一个弦分理论，该理论在仪表理论和弦理论之间进行了插值。我们将使用内部通量研究弦理论的扭曲压缩，以便理解超对称性破裂的现场理论。我们将研究字符串理论中的非交换性及其与非交流性几何形状的联系。这些理论将如何影响宇宙微波背景。我们还将研究黑洞的量子物理学。我们将把注意力集中在三维规程的理论上，尤其是有兴趣理解强烈的耦合二元性。我们还将研究大N膜理论。
