The aim of this paper is to show, using the reflection principle, three new cardinal inequalities. These results improve some well-known bounds on the cardinality of Hausdorff spaces.
A generic theorem in cardinal function inequalities

Similarity:
We establish a general technical result, which provides an algorithm to prove cardinal inequalities and relative versions of cardinal inequalities.
Some Remarks on Tall Cardinals and Failures of GCH

Bulletin of the Polish Academy of Sciences. Mathematics
Similarity:
We investigate two global GCH patterns which are consistent with the existence of a tall cardinal, and also present some related open questions.

Some applications of Sargsyan's equiconsistency method
Arthur W. Apter (2012)
Fundamenta Mathematicae
Similarity:
We apply techniques due to Sargsyan to reduce the consistency strength of the assumptions used to establish an indestructibility theorem for supercompactness. We then show how these and additional techniques due to Sargsyan may be employed to establish an equiconsistency for a related indestructibility theorem for strongness.
