Three physicists wanted to calculate how neutrinos change. They ended up discovering an unexpected relationship between some of the most ubiquitous objects in math. After breakfast one morning in ...

Inverse eigenvalue problems concern the reconstruction of a matrix from prescribed spectral characteristics. Central to this area is the question of existence and uniqueness: given a set of ...

I just got done with my matrix algebra final. I think I did really shitty. But I had to pee really bad the whole time, so it wasn't entirely my fault. This problem in particular was difficult: A ...

Eigenvalue optimisation in differential equations concerns the systematic adjustment of parameters, domain shapes or material distributions to extremise spectral quantities associated with a linear ...
