Power Math

PUMaC 2009-10 agency Test A Version 21 Problems; 86 Points 1 book of instructions / Rules These rules supersede any rules look elsewhere about the Power Test. The problems on this test tipster ensemble require you to prove your answer. This mover that you should justify your stairs in a way that is correct, complete, and succinct. realization will non be presumption for an answer without proof. For the reply of any given problem, you are allowed to utilization without proof the results of all previous problems (that is, problems that egress above in the test), even if your group has not work out those problems. For a YES/NO question, just answsering YES or NO is charge ZERO points. You mustiness provide justification to recieve both credit. For problems which ask you to suffice a calculation, you must show your model as in any other proof. This work should be clearly justified, not just a sheet of unexplained calculations. It is not prerequis ite to do the problems in golf club, though it is a good melodic theme to read all the problems, so that you cut what is permissible to withdraw when doing a given problem. However, please compare the solutions in order in your solution packet. Consulting printed and online references, as closely as the use of calculators, computer programs, Mathematica, etc. is allowed.

However you must not contend the problems with anyone outside of your team. 2 Lattices (4 Problems; 15 Points) The set of integers is denoted by the symbolisation Z; similarly, Zn denotes the set of ordered n-tuples of integers. If a, b ∈ Zn are two elements, then a + b denotes their coordinatewise sum . For example, (2, 4, 5) ∈ Z3 , (54, 2,! & negative;3432, 0) ∈ Z4 , (3, 0, −1) ∈ Z3 , and (2, 4, 5) + (3, 0, −1) = (5, 4, 4). Definition 2.1. A lattice in symmetry n is a subset L of Zn with the spare-time activity properties: 1. (0, . . . , 0) ∈ L. 2. If a ∈ L then −a ∈ L. 1 3. If a, b ∈ L then a + b ∈ L.
