I was born in Totchangni where I spent most of my childhood. I am an undergraduate student in mathematics and computer science at FAST-NATI under UNSTIM In Benin Republic. I have interest in the application of graph theory and this explains why my bachelor project deals with the coloring of graphs and its applications.

I was born in Tanvè, a small town in the commune of Agbangnizoun, Benin Rep. where I spent most of his childhood until I graduated from high school. Passionate about science at the age of 20, I decides to enroll in Mathematics-Computer Science at the Faculty of Sciences and Techniques of Natitingou. There I will meet great teachers who will accompany me through 3 years exceptional. My interest lies in the application of graph theory, topic for my bachelor project with a focus on the applications of the coloring of graphs.

I was born in Porto-Novo where I spent most of my childhood. I am a undergraduate student in Mathematics – Computer Science at FAST-NATI under UNSTIM, in Benin. At the age of 20 I decided to enroll in the rank of scientific researchers. I have an interest in the field of Topology and that in the reason why my undergraduate end of year project relates to: The K-metric space.

##### Emeric Yémalin KINTONOU

**Email:** [email protected]

I was born in Vakon, Benin Rep. where I spent my childhood. My interest broadly includes Mathematics and Data processing. I would like to be part of this great community of scientists and researchers. I am currently enrolled in a 3 year program leading to a bachelor in mathematics and computer science. For my final year project, I am working on the topology metric spaces partial as this serves as a bridge to see how mathematical structures are used in computer science.

##### Gnon Loïse TOUNKARA

**Email:** [email protected]

I have always been passionate about science and medicine, but I enrolled in a science and technology faculty because it suited best my skills as a mathematician and mathematics computer scientist. I am now at the end of the first degree which leads to a bachelor in fundamental mathematics and computer science. I desire to pursue with graduate studies in analysis or the topology, applied to IT.
