    My research works divided into two parts. One part describes basics of Sobolev space. In sobolev part we describes definition of sobolev space, properties of sobolev space, smooth approximation of sobolev function, extension of sobolev function, embedding and compact embedding of sobolev space, Poincar´e Inequality, traces of sobolev functions. In the second parts it describes definition of weak solution of linear elliptic equations, bilinear form, existance and uniqueness of weak solutions by Lax-Milgram’s Theroem, Riesz’s Representation Theroem and Fredholm Alternative Theorem, three kind of regularity of weak solutions and at the end local boudedness of weak solutions by Moser iteration and The De Giorgi-Nash-Moser Theorem.
