*
You are cordially invited to attend *two* colloquia this week given by 
Wilfried Meidl (RICAM, Austria) on *Wednesday, 29 November 2017, in 
FENS-G055 at 11.30 am*, and by İlker İnam (Bilecik Şeyh Edebali 
University) on *Thursday, 30 November 2017, in FENS-L030 **at 11 am.*

Title: Bent functions and generalized Bent functions

Abstract: Bent functions correspond to relative difference sets in the 
groups Zn2 × Z2 respectively Zn2 × Z2m . Being highly nonlinear, Boolean 
bent functions have application in cryptography. Whereas there are many 
constructions of Boolean bent functions, bent functions from Zn2 to Z2m 
seem to be quite rare. Recently a lot of research has been performed on 
generalized bent (gbent) functions, which are functions from Zn2 to Z2m 
satisfying the weaker condi- tion that Hf(1,u) has absolute value 2n/2 
for every u ∈ Zn2. In this talk, the main results on gbent functions and 
bent functions from Zn2 to Z2m are summarized, and some open questions 
are discussed.

Title: Computing with Modular Forms

Abstract: Modular forms are holomorphic functions on the upper half 
plane that satisfy fundamental symmetry and growth conditions. They have 
many applications in several branches of mathem- atics and even in 
physics. Since modular forms are periodic, they are perfect number 
theoretic objects. Furthermore, the space of modular forms are finite 
dimensional vector space, hence they are computation-friendly. In this 
talk, we will introduce modular forms with basic properties and then we 
will show how one can make computations with them by using Magma 
Computer Algebra System.
