2. This is an application of Euler's formula and can produce any unit complex number ( = 1 } } ).
3. That this map is a homomorphism follows from the fact that the multiplication of unit complex numbers corresponds to addition of angles:
4. This follows from the fact that the unit circle is a compact abelian Lie group ( when identified with the unit complex numbers with multiplication ).
5. This has the geometric interpretation that multiplication by a unit complex number is a proper rotation in the complex plane, and every such rotation is of this form.
6. It's difficult to find unit complex numbers in a sentence. 用unit complex numbers造句挺難的

9. The Lawrence Krammer representation preserves a non-degenerate sesquilinear form which is known to be negative-definite Hermitian provided q, t are specialized to suitable unit complex numbers ( " q " near " 1 " and " t " near " i " ).
10. Together with the commutative Lie group of the real numbers, \ mathbb { R }, and that of the unit complex numbers, U ( 1 ), simple Lie groups give the atomic " blocks " that make up all ( finite-dimensional ) connected Lie groups via the operation of group extension.
