I am a third year math phd student who is just beginning research and I have a question about doing research in general.
I would like to work on some projects on my own on the side. I started reading some papers but some are not very new, let's say from the year 2000. Obviously, my goal is to have some ideas about these papers and make extensions, prove conjectures, etc. and publish some of my own.
My question is "If I start reading and thinking about these older papers will I waste alot of time relative to trying to pick papers that are newer due to
- The journal no longer being interested in that line of thought.
- Other people already picking up on those same ideas so I find out someone has already published the work I was trying to do (Naturally there should be a much greater chance of this for older papers since people had more time)
Or do you think the case is that 1 and 2 are negligible and I shouldn't bother restricting my study to new papers.
Thanks
