Abstract algebraic techniques, such as group theory and field theory, are used to answer important questions in geometry and the theory of equations. These applications include the impossibility of trisecting the angle, duplicating the cube, squaring the circle or solving equations of the fifth degree. They also include the possibility of constructing regular polygons with 17,257 and 65,735 sides. There are over 200 exercises, including hints and a selection of solutions equations, theory of,finite fields ( algebra ),galois theory,group theory Minh, 981205 Trung tâm Học liệu Trường Đại học Cần Thơ
