This thesis aims at exploring the consequences of migration in Jhumpa Lahirir¡¦s novel The Namesake. Set in India and America, the story represents such immigrant experiences as the clash of cultures, the conflicts of assimilation, and the tangled ties between generations. In addition to introduction and conclusion, the thesis consists of three chapters, devoted respectively to issues of nostalgia, identity, and cultural hybridity. Chapter One explores the way nostalgia affects the Ganguli family in their daily life, including such aspects as food, clothing, their circle of friends, festivals and celebrations. To analyze Indian immigrants¡¦ longing for home and their attempts to retain homeland culture, I employ Svetlana Boym¡¦s theory on nostalgia, wherein two kinds of nostalgia are distinguished: the restorative and the reflective. Chapter Two focuses on immigrants¡¦ identity formation. The process of identity formation is associated with naming and generational problems. I adopt the Freudian theory of the Oedipus complex to explain the father-son conflicts: how the protagonist defies his father as well as the name given by him. Then, drawing upon Cathy Caruth¡¦s concept of traumatic awakening, I trace how the protagonist reconciles with his father and reaches maturity. Chapter Three examines how immigrants come to invent a hybrid cultural identity. I employ Homi Bhabha¡¦s concepts of in-bewteenness and the Third Space to point out the interplay of the Bengali heritage and the dominant American culture, which results in the phenomenon of a new, dynamic, and mixed culture. With globalization, borders and boundaries are constantly changing so that migration comes to be typical of human condition. In this sense, the immigrant experience stated in The Namesake foregrounds problems which might be encountered by all diasporas.
