A search of stringy maths tachyon papers brought to light this fantastic 2004 paper, with tachyons appearing when legs cross in a $(p,q)$ web diagram.
Looks familiar, doesn't it? These webs are supposed to describe stringy brane configurations, but as usual we will think of them as toric variety diagrams. The paper discusses getting rid of tachyons, but do we need to?
