Representations as Sums of Icosahedral and Dodecahedral Numbers: Proof of Pollock's Conjectures
Debmalya Basak, Anji Dong, Katerina Saettone +1
On the occasion of George Andrews' and Bruce Berndt's combined 170th birthday, we prove two conjectures of Sir Frederick Pollock that are more than 170 years old. In 1843, Pollock…
Constraining Early Dark Energy cosmological models with Big Bang Nucleosynthesis
Teodora M. Matei, Cristian Croitoru, Tiberiu Harko
The recent cosmological picture contains a significant tension indicating that our standard CDM picture may be incomplete. Early Dark Energy models can alleviate the Hubble tens…
Dark matter heating of Planet 9, and its observational implications
Tiberiu Harko
The observed unusual behaviors of the orbits of Trans-Neptunian objects as well as the gravitational anomalies detected by the Optical Gravitational Lensing Experiment can be expla…
Exact general relativistic solutions for a cylindrically symmetric stiff fluid matter source
Tiberiu Harko, Francisco S. N. Lobo, Man Kwong Mak
In this work, we derive the general solutions for a cylindrically symmetric space-time filled with a cosmological perfect fluid obeying (), where repres…
Bridges connecting Encryption Schemes
Mugurel Barcau, Cristian Lupascu, Vicentiu Pasol +1
The present work investigates a type of morphisms between encryption schemes, called bridges. By associating an encryption scheme to every such bridge, we define and examine their…
Is Dark Energy Dynamical in the DESI Era? A Critical Review
Salvatore Capozziello, Himanshu Chaudhary, Tiberiu Harko +1
We investigate whether the recent DESI DR2 measurements provide or not evidences for dynamical dark energy by exploring the CDM model and its extensions with free $\sum m_ν…
