Mathematical conceptualism
Nik Weaver
This is an explanation and defense of "mathematical conceptualism" for a general mathematical and philosophical audience. I make a case that it is cogent, rigorous, attractive, and…
Analysis in J_2
Nik Weaver
This is an expository paper in which I explain how core mathematics, particularly abstract analysis, can be developed within a concrete countable set J_2 (the second set in Jensen'…
Operator algebras associated with the Klein-Gordon position representation in relativistic quantum mechanics
Nik Weaver
We initiate a mathematically rigorous study of Klein-Gordon position operators in single-particle relativistic quantum mechanics. Although not self-adjoint, these operators have re…
Set theory and cyclic vectors
Nik Weaver
Let H be a separable, infinite dimensional Hilbert space and let S be a countable subset of H. Then most positive operators on H have the property that every nonzero vector in the…
A prime C*-algebra that is not primitive
Nik Weaver
We construct a non-separable C*-algebra that is prime but not primitive.
A counterexample to a conjecture of Akemann and Anderson
Nik Weaver
Akemann and Anderson made a conjecture about ``paving'' projections in finite dimensional matrix algebras which, if true, would settle the well-known Kadison-Singer problem. We fal…
