Ratio bound (Lovász number) versus inertia bound

Ferdinand Ihringer

Matthew Kwan and Yuval Wigderson showed that for an infinite family of graphs, the Lovász number gives an upper bound of for the size of an independent set (where …

The classification of Boolean degree functions in high-dimensional finite vector spaces

Ferdinand Ihringer

We classify the Boolean degree functions of -spaces in a vector space of dimension (also known as Cameron-Liebler classes) over the field with elements for $n \geq n…

Regular sets of lines in rank 3 polar spaces

Ferdinand Ihringer, Morgan Rodgers

There are 6 families of finite polar spaces of rank . The set of lines in a rank polar space form a rank association scheme. We determine the regular sets of minimal siz…

Local recognition of the point graphs of some Lie incidence geometries

Ferdinand Ihringer, Paulien Jansen, Linde Lambrecht +4

Given a finite Lie incidence geometry which is either a polar space of rank at least or a strong parapolar space of symplectic rank at least and diameter at most , or th…

On MSR Subspace Families of Lines

Ferdinand Ihringer

A minimum storage regenerating (MSR) subspace family of is a set of -spaces in such that for any -space in $\mathcal…

The strongly regular twisted graph

Ferdinand Ihringer

We construct a new family of strongly regular graphs with the same parameters as the strongly regular graphs . The construction can be seen as a variant of the construc…
