Set theory aims at proving interesting true statements about the mathematical universe. Different people interpret “interesting ” in different ways. It is well known that set theory comes from...
Woodin’s axiom (∗), bounded forcing axioms, and precipitous ideals on ω1 (2010)
Benjamin Claverie, Ralf Schindler
If the Bounded Proper Forcing Axiom BPFA holds, then Mouse Reflection holds at ℵ2 with respect to all mouse operators up to the level of Woodin cardinals in the next ZFC–model. This yields that...
Ronald Jensen, Ernest Schimmerling, Ralf Schindler, John Steel
We show that either of the following hypotheses imply that there is an inner model with a proper class of strong cardinals and a proper class of Woodin cardinals. 1) There is a countably closed...
The self-iterability of L[E (2010)
Let L[E] be an iterable tame extender model. We analyze to which extent L[E] knows fragments of its own iteration strategy. Specifically, we prove that inside L[E], for every cardinal κ which is not...
Increasing u2 by a stationary set preserving forcing (2010)
Benjamin Claverie, Ralf Schindler, Universität Münster
We show that if I is a precipitous ideal on ω1 and if θ> ω1 is a regular cardinal, then there is a forcing P = P(I, θ) which preserves the stationarity of all I-positive sets such that in V P,...
The Extender Algebra and Vagaries of Σ 2 1 Absoluteness (2010)
We review the construction of the extender algebra, a Boolean algebra which is due to Woodin, with δ-many generators. The resulting genericity iteration is applied to prove a new Σ 2 1-absoluteness...

Iterates of the core model (2006)
Let N be a transitive model of ZFC such that ω N ⊂ N and 𝒫(ℝ) ⊂ N. Assume that both V and N satisfy “the core model K exists.” Then KN is an iterate of K, i.e., there exists an...
Using core model theory, we give a proof of Woodin’s theorem that the consistency of AD implies the consistency of infinitely many Woodin cardinals. The proof uses a mouse set theorem which is...
P != NP {cap} co-NP for Infinite Time Turing Machines (2005)
Deolalikar, Vinay, Hamkins, Joel David, Schindler, Ralf
Extending results of Schindler, Hamkins and Welch, we establish in the context of infinite time Turing machines that P is properly contained in NP ∩ co-NP. For higher analogues of these classes, we...
A universal extender model without large cardinals in V (2004)
Mitchell, William, Schindler, Ralf
We construct, assuming that there is no inner model with a Woodin cardinal but without any large cardinal assumption, a model Kc which is iterable for set length iterations, which is universal with...
Causes and therapy of microinflammation in renal failure (2004)
Microinflammation in renal failure has been the subject of numerous studies, but the causes of the inflammatory response in these patients are not clear. There are several potential causes and...
Homogeneously Souslin sets in small inner models (2003)
Koepke, Peter, Schindler, Ralf
We prove that every homogeneously Souslin set is coanalytic provided that either (a) 0^long does not exist or else (b) V=K where K is the core model below a \mu-measurable cardinal.
BMM is stronger than BSPFA (2003)
It is shown that if BMM (= Bounded Martin's Maximum) holds then each set is contained in an inner model with a strong cardinal. This answers a question that has been asked by various people. It...
Universally Baire sets and definable well-orderings of the reals (2003)
Friedman, Sy D., Schindler, Ralf
Let n ≥ 3 be an integer. We show that it is consistent (relative to the consistency of n-2 strong cardinals) that every σ1n-set of reals is universally Baire yet there is a (lightface) projective...
Core models in the presence of Woodin cardinals (2003)
It is shown that if there is a measurable cardinal above n Woodin cardinals and M_{n+1}^# doesn't exist then K exists. K is not fully iterable, though, but only iterable with respect to stacks of...

Cardinal arithmetic and Woodin cardinals (2002)
Suppose that there is a measurable cardinal. If \aleph_\omega is a strong limit cardinal, but the power of \aleph_\omega is bigger than \aleph_{\omega_1}, then there is an inner model with a Woodin...
Sharps and the \Sigma^1_3 correctness of K (2002)
Steel and Welch have shown that K is \Sigma^1_3 correct if the reals are closed under sharps but 0^\pistol doesn't exist. We'll give a simple and purely combinatorial proof of the following: K is...
A simple proof of \Sigma^1_3 correctness of K (2002)
We present a simple and purely combinatorial proof of Steel's result according to which the core model is \Sigma^1_3 correct under the appropriate hypotheses.
P not= NP for infinite time Turing machines (2001)
We state a version of the P=?NP problem for infinite time Turing machines. It is observed that P not= NP for this version.
\nabla_\kappa, remarkable cardinals, and 0^# (2001)
For an uncountable regular cardinal \kappa we let \nabla_\kappa(A) be the statement that A \subset \kappa and for all regular \theta > \kappa, the set of all X \in [\theta]^
More on mutual stationarity (2001)
Extending a result of Foreman and Magidor we prove that in the core model for almost linear iterations the following holds. There is a sequence (S^n_\alpha : n0) such that each individual S^n_\alpha...

Background. Although the capability of extracorporeal treatments after administration of contrast media to prevent radiocontrast‐induced nephropathy is controversial, haemodialysis is...
A universal weasel without large cardinals in V (2000)
We prove in the theory "ZFC + there is no inner model with a Woodin cardinal" that there is a universal weasel. This shows in particular that one doesn't have to assume the existence of large...
A note on an alleged proof of the relative consistency of P=NP with PA (2000)
We indicate that an argument of da Costa and Doria in fact proves P=NP. This observation makes their argument appear dubious. We isolate a weak version of one of their lemmas which would already...

L(R) absoluteness under proper forcings (1999)
We isolate a new large cardinal concept, "remarkability." Consistencywise, remarkable cardinals are between ineffable and omega-Erdos cardinals. They are characterized by the existence of...
The consistency strength of projective uniformization, revisited (1997)
It is shown that if every projective set of reals is Lebesgue measurable and has the property of Baire, if every projective set in the plane has a projective uniformization, and if Steel's K exists,...
Coding into K by reasonable forcing (1997)
Assuming that there is no inner model with a strong cardinal, the following is shown: any subset of \omega_1 can be made \Delta^1_3 (in the codes) by a reasonable set-forcing; there is a reasonable...
Weak covering and the tree property (1997)
Suppose that there's no transitive model of ZFC + there's a strong cardinal, and let K denote the core model. It is shown that if \delta has the tree property then \delta^{+K} = \delta^+ and \delta...
