Summary: We study half light-like submanifolds \(M\) of an indefinite trans-Sasakian manifold such that its structure vector field is tangent to \(M\). First we study the general theory for such half light-like submanifolds. Next we prove some characterization theorems for half light-like submanifolds of an indefinite generalized Sasakian space form.
