Implication

Theoretical analysis demonstrates negative complexity factors for pure Type II matter in generalized Vaidya spacetime, highlighting fundamental differences between matter field classes.

Key Points

To calculate gravitational complexity and derive the structure scalars of a Type II fluid in generalized Vaidya geometry.
Applied a general semi-tetrad 1+1+2 covariant framework to evaluate structure scalars of a Type II fluid.
Calculated the gravitational complexity factor using the Misner–Sharp mass and dynamic matter variables.
Derived the propagation, evolution, and wave equations governing structure scalars and the gravitational mass of the 2-shell.
Identified a non-trivial class of generalized Vaidya spacetimes characterized by vanishing gravitational complexity.
Demonstrated that Vaidya spacetime sourced by a pure Type II matter field yields a negative complexity factor, unlike Type I fields.
Established the kinematic interdependencies among structure scalars through their propagation and evolution equations.
