Entorhinal Silencing Reveals Energy Cascade Organization of Hippocampal Oscillations

open access: yesHippocampus, Volume 36, Issue 1, January 2026.
ABSTRACT Hippocampal theta and gamma rhythms are often viewed as discrete channels supporting distinct cognitive operations. In particular, “gamma multiplexing” models propose that slow and fast gamma bands independently encode separate information streams or memory processes.

Steiner Triple Systems With High Discrepancy

open access: yesJournal of Combinatorial Designs, Volume 34, Issue 1, Page 5-14, January 2026.
ABSTRACT In this paper, we initiate the study of discrepancy questions for combinatorial designs. Specifically, we show that, for every fixed r ≥ 3 and n ≡ 1 , 3 ( mod 6 ), any r‐colouring of the triples on [ n ] admits a Steiner triple system of order n with discrepancy Ω ( n 2 ).

An Approach to the Girth Problem in Cubic Graphs

open access: yesJournal of Graph Theory, Volume 111, Issue 1, Page 17-26, January 2026.
ABSTRACT We offer a new, gradual approach to the largest girth problem for cubic graphs. It is easily observed that the largest possible girth of all n‐vertex cubic graphs is attained by a 2‐connected graph G = ( V , E ). By Petersen's graph theorem, E is the disjoint union of a 2‐factor and a perfect matching M.

Random Lie bracket on sl2(Fp)

open access: yesRandom Structures &Algorithms, Volume 68, Issue 1, January 2026.
ABSTRACT We study a random walk on the Lie algebra sl2(Fp)$$ {\mathfrak{sl}}_2\left({\mathbf{F}}_p\right) $$ where new elements are produced by randomly applying adjoint operators of two generators. Focusing on the generic case where the generators are selected at random, we analyze the limiting distribution of the random walk and the speed at which it
