Toward a simultaneous resolution of the and tensions: early dark energy and an interacting dark sector model
Mai Yashiki
The tension between the Hubble constant () inferred from the cosmic microwave background (CMB) and that measured from late-time observations, such as the local distance ladder…
Nambu Dynamics and Hydrodynamics of Granular Material
Akio Sugamoto, Kazuharu Bamba, Tetuya Kawamura +3
On the basis of the intimate relation between Nambu dynamics and the hydrodynamics, the hydrodynamics on a non-commutative space (obtained by the quantization of space), proposed b…
Unit Ball Graphs on Geodesic Spaces
Masamichi Kuroda, Shuhei Tsujie
Consider finitely many points in a geodesic space. If the distance of two points is less than a fixed threshold, then we regard these two points as "near". Connecting near points w…
Monomial generalized almost perfect nonlinear functions
Masamichi Kuroda
Generalized almost perfect nonlinear (GAPN) functions were defined to satisfy some generalizations of basic properties of almost perfect nonlinear (APN) functions for even characte…
