. that maximal or- ders always exist in finite-dimensional semisimple algebras. Recall that a semisimple K -algebra is the direct sum of a finite number of simple (not necessarily central) K-algebras.. local lattice has a base over 0,. The definition of order and maximal order in a finite-dimensional K, -algebra is now for- mulated in the obvious way. Clearly, if L is a lattice in a finite-di...

Notice that any complex number can be written as a Gaussian inte- ger plus a complex number whose real and imaginary parts are each between 4 and - i. Show that this means that we can divide....

. have a | b and b | a if and only if a = ±b. In particular, for every a ∈ Z, we have a | 1 if and only if a = ±1. Proof. Clearly, if a = ±b, then a | b and b | a. So let us assume that a | b and b. aZ and (az)z  = a( zz  ) ∈ aZ. The ideal aZ is called the ideal generated by a, and an ideal of the form aZ for some a ∈ Z is called a principal ideal. Observe that for all a, b ∈ Z, we have. is...
