Cardinal Characteristics on Large Cardinals
Fundamenta Mathematicae, 2021Das Studium von Kardinalzahlcharakteristiken auf regul ren berabz hlbaren Kardinalzahlen hat in den letzten zehn Jahren erheblich an Popularit t gewonnen. Die Verallgemeinerungen des Cantor- und Baire-Raums auf regul re berabz hlbare Kardinalzahlen kappa induzieren auf nat rliche Weise Verallgemeinerungen der zugeh rigen ...

AbstractThe HOD Dichotomy Theorem states that if there is an extendible cardinal, δ, then either HOD is “close” to V (in the sense that it correctly computes successors of singular cardinals greater than δ) or HOD is “far” from V (in the sense that all regular cardinals greater than or equal to δ are measurable in HOD).

GENERICITY AND LARGE CARDINALS
Journal of Mathematical Logic, 2005We lift Jensen's coding method into the context of Woodin cardinals. By a theorem of Woodin, any real which preserves a "strong witness" to Woodinness is set-generic. We show however that there are class-generic reals which are not set-generic but preserve Woodinness, using "weak witnesses".

Are Large Cardinal Axioms Restrictive?
Philosophia Mathematica, 2023AbstractThe independence phenomenon in set theory, while pervasive, can be partially addressed through the use of large cardinal axioms. A commonly assumed idea is that large cardinal axioms are species of maximality principles. In this paper I question this claim.

Intensionality, Reflection, and Large Cardinals
Siberian Mathematical Journal, 2002The authors study some axiomatic systems of set theory in which the reflection principle is postulated for all formulas without class quantifiers. These systems are interesting because in some of them the existence of large cardinals can be proven. Some aspects of interpretability of these theories in classical systems and in each other are considered.

Inner Models and Large Cardinals
Bulletin of Symbolic Logic, 1995In this paper, we sketch the development of two important themes of modern set theory, both of which can be regarded as growing out of work of Kurt Gödel. We begin with a review of some basic

Large Cardinal Properties of Small Cardinals
1998The fact that small cardinals (for example N1 and N2) can consistently have properties similar to those of large cardinals (for example measurable or supercompact cardinals) is a recurring theme in set theory. In these notes I discuss three examples of this phenomenon; stationary reflection, saturated ideals and the tree property.

Weak Covering at Large Cardinals
Mathematical Logic Quarterly, 1997AbstractWe show that weakly compact cardinals are the smallest large cardinals k where k+ < k+ is impossible provided 0# does not exist. We also show that if k+Kc < k+ for some k being weakly compact (where Kc is the countably complete core model below one strong cardinal), then there is a transitive set M with M ⊨ ZFC + “there is a strong ...

Publisher Summary This chapter discusses sequentially large cardinals. Large cardinals defined via elementary embeddings are the largest cardinals and the strongest in terms of relative consistency strength. The chapter defines the sequentially large cardinals are defined, a spectrum of large cardinals that are defined via elementary embeddings, in ...

Large cardinals and large dilators
Journal of Symbolic Logic, 1998AbstractApplying Woodin's non-stationary tower notion of forcing, I prove that the existence of a supercompact cardinal κ in V and a Ramsey dilator in some small forcing extension V[G] implies the existence in V of a measurable dilator of size κ, measurable by κ-complete measures.
