Abstract: We will discuss the following basic question: how can one determine if two quadratic forms with coefficients in a field are equivalent? In order to study this question, quadratic forms are often studied using their invariants living in suitable groups. Time permitting, we will describe some deep results about the classification of quadratic forms proved in the last 20-25 years and discuss some examples. |
