Groupsalso called their . under the law of composition, and will be denoted by .. (Sometimes, we also write . · ., and in many cases it is also convenient to use an additive notation, and thus to write . + .. In that case, we call this element the . of . and .. It is customary to use the notation . + . only when the relation . + . = . + . holds.)

Algebraic Extensionshere the polynomial has a root, and we prove the existence of an algebraic closure. We make a preliminary study of such extensions, including the automorphisms, and we give algebraic extensions of finite fields as examples.

Structure of Bilinear Forms theorems giving normalized expressions for these forms with respect to suitable bases. The chapter also follows the standard pattern of decomposing an object into a direct sum of simple objects, insofar as possible.
