There are five chapters in this book. Basic terminologies and graphicparameters are introduced in Chapter 1. We show some results on fractionalfactors of graphs in Chapter 2. We investigate fractional deleted graphs in Chapter3. We present some theorems related to fractional （k，m）-deleted graphs inChapter 4. We study fractional （g，f，m）-deleted graphs in Chapter 5. This book is primarily aimed at researchers and graduate students in graphtheory.
