Chris LambieHanson is a postdoctoral fellow in the Department of Mathematics and Applied Mathematics at Virginia Commonwealth University.
He received his PhD from Carnegie Mellon University in May 2014, working with James Cummings.
His research interests primarily lie in set theory, in particular forcing, large cardinals, and combinatorial set theory.

Chris LambieHanson: Squares, ascent paths, and chain conditions
BIU seminar in Set Theory
On 06/11/2017, 1315, Building 505, Room 65
Speaker: Chris LambieHanson
Title: Squares, ascent paths, and chain conditions
Abstract. Two topics of interest in modern set theory are the productivity of chain conditions and the existence of higher Aronszajn trees. continue reading…

Chris LambieHanson: A forcing axiom deciding the generalized Souslin Hypothesis
Mathematical logic seminar – Oct 3 2017
Time: 3:30pm – 4:30 pm
Room: Wean Hall 8220
Speaker: Chris LambieHanson
Department of Mathematics
BarIlan University
Title: A forcing axiom deciding the generalized Souslin Hypothesis
Abstract:
Given a regular, uncountable cardinal $\kappa$, it is often desirable to be able to construct objects of size $\kappa^+$ using approximations of size less than $\kappa$. continue reading…
Chris LambieHanson: Constructions from square and diamond, with an application to superSouslin trees
Monday, May 8, 2017, 16.30
Seminar room 0.011, Mathematical Institute, University of Bonn
Speaker: Chris LambieHanson (BarIlan)
Title: Constructions from square and diamond, with an application to superSouslin trees
Abstract. In 1982, Shelah and Stanley proved that, if $\kappa$ is a regular, infinite cardinal, $2^\kappa = \kappa^+$, and there is a $(\kappa^+, 1)$morass, then there is a $\kappa^{++}$superSouslin tree, which is a type of normal $\kappa^{++}$tree that necessarily has a $\kappa^{++}$Souslin subtree and continues to do so in any outer model in which $\kappa^{++}$ is preserved and no new subsets of $\kappa$ are present. continue reading…
Chris LambieHanson: Partition relations and generalized scattered orders
BIU seminar in Set Theory
On 30/03/2017, 1012, Building 604, Room 103
Speaker: Chris LambieHanson
Title: Partition relations and generalized scattered orders
Abstract: The class of scattered linear orders, isolated by Hausdorff, plays a prominent role in the study of general linear orders. continue reading…
Chris LambieHanson: Trees with ascent paths
HUJI Logic Seminar
The next meeting of the Logic Seminar will be in Wednesday, 22/03/17, 16:00 – 18:00, Ross buiding.
Speaker: Chris LambieHanson
Title: Reflections on the coloring and chromatic numbers
Abstract: The notion of an ascent path through a tree, isolated by Laver, is a generalization of the notion of a cofinal branch and, in many cases, the existence of an ascent path through a tree provides a concrete obstruction to the tree being special. continue reading…
Chris LambieHanson: Reflections on the coloring and chromatic numbers
HUJI Logic Seminar
The next meeting of the Logic Seminar will be in Wednesday, 18/01, 16:00 – 18:00, Ross 70.
Speaker: Chris LambieHanson
Title: Reflections on the coloring and chromatic numbers
Abstract: Compactness phenomena play a central role in modern set theory, and the investigation of compactness and incompactness for the coloring and chromatic numbers of graphs has been a thriving area of research since the mid20th century,when De Bruijn and Erdős published their compactness theorem for finite chromatic numbers. continue reading…
