For the first time, the March SAT was completely digital and adaptive. Each student taking the test got easier or harder questions depending on whether or not they correctly answered previous ...

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 ...

This paper is based on work of Rees on integral closures of modules and initiates the study of integrally closed modules over two-dimensional regular local rings in analogy with the classical theory ...
