On multi-propagator angular integrals

Juliane Haug, Vladimir A. Smirnov, Fabian Wunder

We study multi-propagator angular integrals, a class of phase-space integrals relevant to processes with multiple observed final states and a test-bed for transferring loop-integra…

eSASRec: Enhancing Transformer-based Recommendations in a Modular Fashion

Daria Tikhonovich, Nikita Zelinskiy, Aleksandr V. Petrov +4

Since their introduction, Transformer-based models, such as SASRec and BERT4Rec, have become common baselines for sequential recommendations, surpassing earlier neural and non-neur…

Integrability of the magnetic geodesic flow on the sphere with a constant 2-form

Alexey V. Bolsinov, Andrey Yu. Konyaev, Vladimir S. Matveev

We prove a recent conjecture of Dragovic et al arXiv2504.20515 stating that the magnetic geodesic flow on the standard sphere whose magnetic 2-form is…

Symplectic classification for universal unfoldings of singularities in integrable systems

Elena A. Kudryavtseva

In the present paper, we obtain real-analytic symplectic normal forms for integrable Hamiltonian systems with degrees of freedom near singular points having the type ``universa…

Inverse Problem for the Schrödinger Equation with Non-self-adjoint Matrix Potential

Sergei Avdonin, Alexander Mikhaylov, Victor Mikhaylov +1

We consider the dynamical system with boundary control for the vector Schrödinger equation on the interval with a non-self-adjoint matrix potential. For this system, we study the i…

Bifurcations of magnetic geodesic flows on surfaces of revolution

Ivan F. Kobtsev, Elena A. Kudryavtseva

We study magnetic geodesic flows invariant under rotations on the 2-sphere. The dynamical system is given by a generic pair of functions in one variable. Topology of the Li…

First Look at Quartic-in-Spin Binary Dynamics at Third Post-Minkowskian Order

Dogan Akpinar, Fernando Febres Cordero, Manfred Kraus +2

We compute the conservative and radiation-reaction contributions to classical observables in the gravitational scattering between a spinning and a spinless black hole to the fourth…
