    The fixed point and the Craig interpolation properties for sublogics of $$\textbf{IL}$$.Sohei Iwata, Taishi Kurahashi & Yuya Okawa - 2024 - Archive for Mathematical Logic 63 (1):1-37.
    We study the fixed point property and the Craig interpolation property for sublogics of the interpretability logic \(\textbf{IL}\). We provide a complete description of these sublogics concerning the uniqueness of fixed points, the fixed point property and the Craig interpolation property.
