## Abstract:

For $1\le p \le q<\infty$, we define the Morrey space $\mathcal{M}^p_q({\mathbb R}^n)$ to be the set of all $p$-locally integrable functions on ${\mathbb R}^n$ such that

\[ \| f \|_{{\mathcal M}^p_q} := \sup_{B \subset \mathbb{R}^n} |B|^{\frac{1}{q}-\frac{1}{p}} \left(\int_{B}|f(y)|^ \,dy\right)^\frac{1}{p}<\infty, \]

where the supremum is taken over all balls $B=B(a,r)$ in ${\mathbb R}^n$. By using the distribution function instead of the integral, one may also define the weak Morrey space $w{\mathcal M}^p_q({\mathbb R}^n)$. In this talk, I would like to discuss about the inclusion relation among Morrey spaces, as well as between Morrey spaces and weak Morrey spaces.
