Abstract

In this chapter, I make an overview of the current knowledge about dwarf galaxies and their evolution in the cluster environment, and describe some of the open questions of the field. I start by defining dwarf galaxies and their morphological types and shortly introduce the observational framework of the field. I then describe the main environmental effects taking place in galaxy clusters and how they shape the dwarf galaxy populations in them. In addition, I give an introduction to the Fornax Deep Survey and shortly review the previous studies addressing the Fornax cluster, which plays a major role in the scientific chapters of this thesis. Finally, I summarize the contents of this thesis and how it tries to answer the open questions in the dwarf galaxy evolution.
