Metrics Over Merit: The Hidden Costs of Citation Impact in Research
Vugar Ismailov
Once upon a time, scientists' worth was measured by their ideas, proofs, and perhaps how eloquently they debated Hilbert's problems at seminars. But now, citation metrics have come…
On shallow feedforward neural networks with inputs from a topological space
Vugar Ismailov
We study feedforward neural networks with inputs from a topological space (TFNNs). We prove a universal approximation theorem for shallow TFNNs, which demonstrates their capacity t…
Dynamic scaling and Family-Vicsek universality in quantum spin chains
Cătălin Paşcu Moca, Balázs Dóra, Doru Sticlet +3
The Family-Vicsek scaling is a fundamental framework for understanding surface growth in non-equilibrium classical systems, providing a universal description of temporal surface ro…
Loss-induced quantum information jet in an infinite temperature Hubbard chain
Patrik Penc, Cătălin Paşcu Moca, Örs Legeza +3
Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly i…
Measure theoretic results for approximation by neural networks with limited weights
Vugar Ismailov, Ekrem Savas
In this paper, we study approximation properties of single hidden layer neural networks with weights varying on finitely many directions and thresholds from an open interval. We ob…

Khalig M. Aslanov, Nigar M. Aslanova
We investigate minimal operator corresponding to operator differential expression with exit from space, study its selfadjoint extensions, also for one particular selfadjoint extens…
Inverse square singularities and eigenparameter dependent boundary conditions are two sides of the same coin
Namig J. Guliyev
We show that inverse square singularities can be treated as boundary conditions containing rational Herglotz--Nevanlinna functions of the eigenvalue parameter with "a negative numb…
