Singular Solutions to Special Lagrangian Equations with Subcritical   Phases and Minimal Surface Systems
  We construct singular solutions to special Lagrangian equa- tions with subcritical phases and minimal surface systems. A priori estimate breaking families of smooth solutions are also produced cor- respondingly. A priori estimates for special Lagrangian equations with certain convexity are largely known by now.
