  1. Henryk Kotlarski (1996). An Addition to Rosser's Theorem. Journal of Symbolic Logic 61 (1):285-292.
    For a primitive recursive consistent and strong enough theory T we construct an independent statement which has some clear metamathematical meaning.

  3. Henryk Kotlarski (1994). On the Incompleteness Theorems. Journal of Symbolic Logic 59 (4):1414-1419.
    We give new proofs of both incompleteness theorems. We do not use the diagonalization lemma, but work with some quickly growing functions instead.

  6. Henryk Kotlarski (1984). Some Remarks on Initial Segments in Models of Peano Arithmetic. Journal of Symbolic Logic 49 (3):955-960.
    If $M \models PA (= Peano Arithmetic)$ , we set $A^M = \{N \subset_e M: N \models PA\}$ and study this family.

  7. Henryk Kotlarski (1983). On Cofinal Extensions of Models of Arithmetic. Journal of Symbolic Logic 48 (2):253-262.
    We study cofinal extensions of models of arithmetic, in particular we show that some properties near to expandability are preserved under cofinal extensions.
