An edge e of a graph G is called deletable for some orientation o if
the restriction of o to G−e is a strong orientation. Inspired by a problem
of Frank, in 2021 H\"orsch and Szigeti proposed a new parameter for
3-edge-connected...

Caches at CPU nodes in disaggregated memory architectures amortize the high
data access latency over the network. However, such caches are fundamentally
unable to improve performance for workloads requiring pointer traversals across
linked ...

Ethics have become an urgent concern for data science research, practice, and
instruction in the wake of growing critique of algorithms and systems showing
that they reinforce structural oppression. There has been increasing desire on
the p...

This paper introduces the concepts of spectral influence and spectral
cyclicality, both derived from the largest eigenvalue of a graph's adjacency
matrix. These two novel centrality measures capture both diffusion and
interdependence from a...

Let ℓ≥5 be a prime number and Fℓ denote the finite
field with ℓ elements. We show that the number of Galois extensions of the
rationals with Galois group isomorphic to GL2(Fℓ) and absolute

For any (possibly singular) hyperelliptic curve, we give the definition of a
hyperelliptic refined spectral curve and the hyperelliptic refined topological
recursion, generalising the formulation for a special class of genus-zero
curves by ...
An extension of Steinberg's Theorem to biquotient pairs of subgroups

We study the derived tensor product of the representation rings of subgroups
of a given compact Lie group G. That is, given two such subgroups H_1 and H_2,
we study the tensor product of the associated representation rings R(H_1) and
R(H_2)...

Microscopically understanding competing orders in strongly correlated systems
is a key challenge in modern quantum many-body physics. For example, the study
of magnetic polarons and their relation to pairing in the Fermi-Hubbard model

History and Philosophy of Physics
There is an odd tension in electroweak physics. Perturbation theory is
extremely successful. At the same time, fundamental field theory gives manifold
reasons why this should not be the case. This tension is resolved by the
Fr\"ohlich-Morch...
