On one hand, local fields form the class of fields which is the next most easiest to study after the class of finite fields, and hence they are quite useful for and applicable in many parts of mathematics, on the other hand, local fields show up in the local study of various parts of mathematics including number theory, algebraic geometry, algebraic topology and areas of mathematical physics. 
 This course will discuss the main examples, features and type of behaviour of local fields and local arithmetic. 


We will discuss the assumed prerequisites soon, some basic knowledge of p-adic numbers will be useful.


p-adic numbers
fields with absolute values and valuations
polynomials over local fields (Hensel's lemma)
extensions of local fields
ramification theory
