Genericity conjecture for disclination-line energy concentration

In the Landau–de Gennes model, let point defects and disclination lines be the two defect forms, with excessive energy concentrated near the defects. Energy-concentration genericity conjecture. Disclination lines are a more generic way for energy concentration than point defects. The conjecture reflects the observed preference for forming a $1/2$-disclination line as an efficient way to reduce the total energy cost, but the source does not state a resolution.
