Hello I'm a software engineer who just wants to start research in mathematics soon. I'm interested in the foundations and hence I'm picking mathematical logic. As I have never touched undergraduate-level maths and I was doing mostly programming since my 11th grade, I accept that I have knowledge gaps. But instead of building my foundations from self-study and thinking about starting research after n years, I want to start soon.
I'm thinking of beginning with the first research papers that usually graduate students get introduced to in mathematical logic and if any material would not make any sense, I will pick up the undergraduate level book on logic and starting build my gaps to understand that part. Even I can pick textbooks from high school level if something in undergrad text won't make sense but "I just want to continue research (or research exploration) and foundations building in parallel".
Hope it will be doable. So could you tell me about first research papers in mathematical logic that I can start reading on? Thanks.
