Homological algebra studies algebraic structures by probing them with chain complexes and derived functors, revealing hidden layers of relationships among objects such as modules over rings.

The Virasoro vertex algebra arises as the symmetry algebra of a two-dimensional conformal field theory. The Virasoro irreducible modules are well-known, and they play a prominent role in rational ...

This module can be used by students to hone their mental math skills using a variety of mathematical operations. The game goes through multiplication, addition, subtraction, algebra, and exponent ...
