I am exploring some new research fields in CS from my unrelated field in math.
Many papers I have stumped upon during research seem to completely ignore the fact that notation and symbols have meanings. Coming from math, this is a bit unsettling to me.
I hate to provide example, but here is one. In equation 1, some magical capital letters are used as functions, but never defined. No references are provided either. Here is another one. Virtually all the symbols which are supposed to mean something in math are not provided with any definition.
I've encountered a whole string (dozens) of these papers in a row.
Is this a common practice in CS? Or perhaps due to page limit? Can anyone explain what I am seeing?
