## Note regarding tutorial 6 | |

In the last tutorial (tutorial 6, Sunday 21/5/17), we've seen a theorem that said that a set of characters of a group Gamma is an orthonormal basis for all functions Gamma->C. This theorem is true only for groups that are finite and abelian, and does not necessarily hold for a group that is not such. The theorem will be stated correctly in the tutorial notes that will be uploaded to the website in the following days. |

## Guidance and clarifications regarding HW2 | |

- Questions 1.1 and 1.2 are independent of each other. - In question 2, the idea is to take any division operation and transform it to a form that suits the form of the algorithm presented in the lecture notes, namely, an algorithm over polynomials. You can refer to the lecture notes in the link under Lecture 4 in the course material section to see the transformation. Once you see it, you should be able to prove its correctness alone. - To solve question 4, follow the proof in the latest lecture notes. The proof there investigates matrix multiplication, and transforms every algorithm for matrix multiplication into an algorithm that works with polynomials. In matrix multiplication, we had polynomials of degree 2 since the output expression involved multiplication. For computing the sum of n inputs we will need to work with polynomials of degree 1 only. Having polynomials of degree 1, we can see that multiplication is not needed (except maybe multiplying with constants). |

## Complementary Tutorial Time | |

Hi all, Since the survey did not help reach an agreement, and due to some requests, the complementary tutorial will be held Sunday 7/5 16:30. The room in which the tutorial will take place will be announced later this week. Students who cannot attend the tutorial can refer to the notes that will be uploaded right after the class, and can always reach out to me for any questions. Tamer |
