dc.description.abstract최근, 경계조건이 있는 등각장론을 연구하는 것은 초끈이론, 통계 물리, 응집 물질 물리 등을 이해하는데 있어서 매우 중요하다. 이를 이해하기 위해, 우선 기본적인 등각장론을 소개하고, 자유 보존계에 대한 경계조건을 갖는 등작장론에 대해 알아본다. 특별히, 자기장과 관련있는 시간 미분 형태의 경계 작용량과 코사인 함수꼴의 위치에너지가 있을 경우의 등각장론에 대해 살펴본다.; The boundary conformal field theories are becoming very important recently for applications to, among others, string theories, statistical physics, and quantum impurity problems. This thesis is devoted to an introduction to conformal field theories of free bosons with various dynamic boundary conditions which correspond to boundary actions containing time-derivatives of the free ¯elds. In particular, we consider the effect of a boundary magnetic flux along with cosine-potential boundary interaction.-
