39 særdeles talentfulde forskere har netop modtaget en Sapere Aude: DFF-Forskningsleder-bevilling fra Danmarks Frie Forskningsfond👏
De lovende forskere står bag forskning i topklasse og skal nu også prøve kræfter som forskningsledere. Tillykke!

Hopf algebras are groups (in the category of vector spaces)

Lie algebras are examples of Hopf algebras (via universal enveloping algebra)

Lie 'algebras' are really groups 🤯

T-duality

There is a finite (as a set) topological space with fundamental group ℤ!

My favorite circular definition: A quiver is a representation of the Kronecker quiver in the category of sets. (The Kronecker quiver has two vertices and two parallel arrows from the first to the second vertex.)

What -2 of something looks like (to an algebraic topologist).
