For each of the following functions determine whether it is the real part of a
differentiable function defined on C. If it is, determine a corresponding imaginary
part.
(i) u(x, y) = x² - y²+4xy;

Let A be an algebra and X C A a subset. Recall that the centraliser of X in
A is defined to be
==
C(X) = {a A | ax = xa for all x = X}.
Let
U =
{ (o b) : a, b, c & R} ≤ M₂(R).
C
as in Question 1.
(i) Show that the centraliser of U in M₂(R) is:
C(U) = {(o 9 ) ; a € R} .

:
(ii) Let M=R2, the natural module for U. Show that Endu (M) = R.
(iii) Find all one-dimensional submodules of M.
(iv) Is MXY for some submodules X, Y of M? (no proof is required for
this part.)
Let A be a finite-dimensional algebra. Prove that A is a semisimple algebra if
and only if every left ideal I of A admits a complement (so there exists a left
ideal J such that A = I J as vector spaces).
You I may assume that if a module M can be written as a sum of simple modules
M =
S₁+ S₂++ Sn, then we can find a subset R C {1, 2, ………, n} such that
DER ST is a direct sum of simples. You may also assume that every
non-zero finite-dimensional module has a simple submodule.

A Sudoku puzzle is a grid of nine by nine squares or cells that have been subdivided into nine "regions" of three by three cells. Consider the following diagram: The objective of Sudoku is to enter a digit from 1 through 9 in each cell, in such a way that: Each horizontal row (shown in blue) contains each digit exactly once. Each vertical column (shown in pink) contains each digit exactly once. Each sub grid or region (shown in orange) contains each digit exactly once. In each Sudoku puzzle, some digits have already been entered, you may not change these. Your job is to fill the remaining cells with digits keeping in mind the three rules discussed above. Sudoku puzzles have become so popular that they can be found in newspapers and magazines around the world.
