Classification is not only based on one or a few features, but you have to consider lots of features in classification of livings. for example plant cells globally have chloroplast, cell wall, and vacuole and have not centrioles. Animals are different in all this features with plants. furtherly plants are autotroph and steady while animals are not. Other organisms are also different in these features or other features with plants and animals.

What's the difference between a plant and an animal?
I really need some opinions/advice on my situation.

My background

I'm studying for my master degree in mathematics. I have always (since I was 14) wanted to do my own research one day. As I grew older, I knew that mathematics was what I wanted to do. So I went to the university to study mathematics. After having encountered a course in group theory I knew that I belonged to the algebraic part of mathematics. I did my bachelor project in group theory and when I became a graduate student (September 2013), I took courses and made a project supporting my interest in algebra.

Along the way I created the vision that I would finish my master degree as a dedicated student in algebra. In order to realize this vision my plan was to study abroad for one semester taking new algebraic courses.

The situation

My situation today is that my study abroad semester begins tomorrow. As mentioned my dream is to do my own research, but more generally/important: I want to develop new ideas and be dedicated to something and I would love to follow/explore my passion.

My first thought (as many other students): I should get a PhD. So I did some research and figured out that there was an available position at the university I'm currently studying at in geometric group theory.

I don't know much about geometric group theory, but I do know that I love group theory. So I would really like to know if this is an opportunity or if I should just forget it.

I don't want to pursue a PhD for anything in this world. I just want to stay focus on creating a meaningful work life around my passion.

Any advice?



Further remarks

I'm a student from Denmark and I'm studying abroad in Austria for one semester. After my study abroad semester I still have to study one year for my master degree in Denmark. However this year consists of a half year with elective courses and a half year where I'm making my master's thesis. 

I don’t know much about the PhD position. I found it from a Google search (: “PhD position group theory”). There is only given a starting date and an e-mail address for contact. I’m going to attend a course held by the supervisor of the project, so the whole thing is a coincidence. 

I have investigated my opportunities for a position at my home university. One of my supervisors, a professor in group theory, told me that he couldn't offer me a position, since it was a question about money, but would like to recommend me. I don't think the university accepts PhD students without a master degree and the positions are without project descriptions.

However there is also another university (in Denmark) with a talent program where it is possible to get a PhD position without having a master degree. I contacted them and they told me I should apply after my study abroad semester (because I would have a stronger profile). But I don't know my chances.
