아래와 같이 세미나를 개최하오니 많이 참석해 주시기 바랍니다. 아 래 1. 제목: Generalised cosmological scaling solutions in braneworld and their duality properties 2. 연사: Lee, Seung Joo (University of Sussex/England) 3. 일시: 2006년 4월 28일(금요일) 오후 3시 4. 장소: 물리학과 세미나실(31355호실) 5. 초록: Motivated by the recent interest in cosmologies arising from energy density modifications to the Friedmann equation, we analyze the scaling behavior for a broad class of these cosmologies comprised of scalar fields and background barotropic fluid sources. In particular, we determine the corresponding scalar field potentials which lead to attractor scaling solutions in a wide class of braneworld and dark energy scenarios. We show how a number of recent proposals for modifying the Friedmann equation can be thought of as being dual to one another, and determine the conditions under which such dualities arise.
