Two-Dimensional Gravity and Nonlinear Gauge Theory

We construct a gauge theory based on nonlinear Lie algebras, which is an extension of the usual gauge theory based on Lie algebras. It is a new approach to generalization of the gauge theory. The two-dimensional gravity is derived from nonlinear Poincaré algebra, which is the new Yang-Mills like formulation of the gravitational theory. As typical examples, we investigate R2 gravity with dynamic...

M-Theory and Two-Dimensional Effective Dynamics

We calculate from M-theory the two-dimensional low energy effective dynamics of various brane configurations. In the first part we study configurations that have a dual description in type IIA string theory as two-dimensional (4, 0) Yang-Mills theories with gauge group SU(N1) × SU(N2) and chiral fermions in the bi-fundamental representation. In the second part we derive related equations of mot...

Topics in Two-Dimensional Field Theory and Heterotic String Theory

We study a myriad of topics related to string theories in two dimensions and/or to heterotic string theories. In chapter 2, we use the duality of two-dimensional string theory with matrix models to study arbitrary time-dependent backgrounds. As an example, we study the case of a Fermi droplet cosmology and analyze properties of the coordinates in which the metric is trivial; we also comment on ...

Deontic Reasoning With Emotional Content: Evolutionary Psychology or Decision Theory?

Three experiments investigated the contrasting predictions of the evolutionary and decision-theoretic approaches to deontic reasoning. Two experiments embedded a hazard management (HM) rule in a social contract scenario that should lead to competition between innate modules. A 3rd experiment used a pure HM task. Threatening material was also introduced into the antecedent, p, of a deontic rule,...
