posts for november 2014.

two days ago, alexander grothendieck, one of the greatest mathematicians of the 20th century, died. i’ve seen a small excerpt of his work in algebraic geometry and commutative algebra during my studies, phd and postdoc times. without his work and ideas, the theory of schemes wouldn’t be what it is today, and without it, the study of elliptic curves over rings might have taken quite a different road. (elliptic curves over rings are a topic i’ve been very interested in while working on my diplom thesis.) even though his active mathematical career stopped over 40 years ago, his work had an immense influence on generations of mathematicians.

rest in peace.

(a great obituary can be read at the telegraph.)
