Decidable Reasoning in First-Order Knowledge Bases with Perfect Introspection
Since knowledge bases (KBs) are usually incomplete, they should be able to provide information regarding their own incompleteness, which requires them to introspect on what they k...

Pure Future Local Temporal Logics Are Expressively Complete for Mazurkiewicz Traces
The paper settles a long standing problem for Mazurkiewicz traces: the pure future local temporal logic defined with the basic modalities exists-next and until is expressively com...

The Undecidability of Boolean BI through Phase Semantics
We solve the open problem of the decidability of Boolean BI logic (BBI), which can be considered as the core of separation and spatial logics. For this, we define a complete phas...
