I recently heard about a branch called tropical geometry developed by Professor Bergman. I was wondering if there´s a newest but yet unexplored math branch, and by newest I mean developed in the last 60 years, and by unexplored I understand a branch without a huge amount of written articles, books, given seminars or courses in the top universities. I am just asking for pure math branch, and not applied math or mathematical physics. Thanks.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.
There's a lot of new and unexplored branches of math. I study finite subdivision rules, which were invented in the 80's and less than 50 papers discussing them explicitly. String theory in it's mathematical form is another.
