The Role of Grid Cells in Reducing Spatial Aliasing in Hippocampal Place Representations
Alexander Johnson, Obadah Ghizawi, Ali A. Minai
Spatial aliasing occurs when two or more distinct locations produce highly similar place-cell representations, primarily due to environmental symmetry or repetitive structures. Thi…

Rigidity of Kantorovich solutions in discrete Optimal Transport
Alexander Bruce Johnson, Stefan Steinerberger
We study optimal transport plans from equally weighted points (with weights ) to equally weighted points (with weights ). The Birkhoff-von Neumann Theorem implies…
