Gagliardo Seminorm and a Number of Atypical Features of Slobodeckij Spaces
Ali Behzadan
UCSD
Abstract:
In this talk we will try to discuss the
following questions:
1. What is the space of distributions? What are its key
properties? Why do we need it? How do we use it?
2. What is a function space? What are the nice properties that
we would like our function spaces to possess?
3. Why is the Gagliardo seminorm defined the way it is?
4. How do interpolation theory and Littlewood-Paley theory come
into play in the study of Slobodeckij spaces?
5. For what values of s and p , \partial^alpha: W^{s,p}(Omega)-->
W^{s-|alpha|,p}(Omega) is a well defined bounded linear
operator for all alpha in N_0^n? Why do we care about
this question?
