A no-go theorem for irreversibility along single-branch collapse dynamics

This paper proves that for finite-dimensional quantum systems undergoing single-branch collapse dynamics without information erasure, operational irreversibility is structurally impossible because every physically admissible collapse selector contains a forward-invariant subset of states that can be connected with arbitrarily high precision and negligible energy cost, thereby establishing islands of quasi-reversibility.

Non-abelian Hodge correspondence over singular Kähler spaces

This paper extends the non-abelian Hodge correspondence to compact Kähler spaces with klt singularities by establishing an equivalence between polystable Higgs bundles and semi-simple flat bundles on regular loci and proving a descent theorem for Higgs bundles along resolutions, ultimately yielding a quasi-uniformization theorem for projective klt varieties satisfying the orbifold Miyaoka-Yau equality.

Single- and Multi-Level Fourier-RQMC Methods for Multivariate Shortfall Risk

This paper introduces a novel class of single- and multi-level Fourier-RQMC algorithms that leverage frequency-domain integration and randomized quasi-Monte Carlo sampling to achieve superior accuracy and computational efficiency in estimating multivariate shortfall risk and optimal capital allocations compared to traditional Monte Carlo methods.
