Noncommutative Riemann Surfaces [PDF]
, 1999 We compactify M(atrix) theory on Riemann surfaces Sigma with genus g>1. Following [1], we construct a projective unitary representation of pi_1(Sigma) realized on L^2(H), with H the upper half-plane. As a first step we introduce a suitably gauged sl_2(R)

Progress in the Molecular Biology of Ewing Tumors
Sarcoma, Volume 2, Issue 1, Page 3-17, 1998., 1998 Purpose/results/discussion. Rearrangement of the EWS gene with an ETS oncogene by chromosomal translocation is a hallmark of the Ewing family of tumors (EFT). Detectability, incidence, tumor specificity and variability of this aberration have been matters of intense investigation in recent years.

Target space entanglement in quantum mechanics of fermions at finite temperature
Journal of High Energy Physics, 2022 We consider the target space entanglement in quantum mechanics of non-interacting fermions at finite temperature. Unlike pure states investigated in [1], the (Rényi) entanglement entropy for thermal states does not follow a simple bound because all ...

Susceptibility of lung epithelium to neutrophil elastase: protection by native inhibitors
Mediators of Inflammation, Volume 6, Issue 5-6, Page 345-354, 1997., 1997 The development of emphysema is thought to be due to an imbalance of proteases (especially neutrophil elastase [NE]) and antiproteases with loosening of the respiratory epithelium as an early event. We investigated the effect of NE on respiratory epithelial cell adherence in vitro , in the presence of varying concentrations and combinations of native ...

Spontaneous symmetry breaking in tensor theories
Journal of High Energy Physics, 2019 In this work we study spontaneous symmetry breaking patterns in tensor models. We focus on the patterns which lead to effective matrix theories transforming in the adjoint of U(N).

Chaos from massive deformations of Yang-Mills matrix models
Journal of High Energy Physics, 2020 We focus on an SU(N ) Yang-Mills gauge theory in 0 + 1-dimensions with the same matrix content as the bosonic part of the BFSS matrix model, but with mass deformation terms breaking the global SO(9) symmetry of the latter to SO(5) × SO(3) × ℤ2 ...

Target space entanglement entropy
Journal of High Energy Physics, 2023 We define a notion of target space entanglement entropy. Rather than partitioning the base space on which the theory is defined, we consider partitions of the target space.

On the quantum mechanics of M (atrix) theory [PDF]
Nuclear Physics B, 1998 We present a study of M(atrix) theory from a purely canonical viewpoint. In particular, we identify free particle asymptotic states of the model corresponding to the supergraviton multiplet of eleven dimensional supergravity. These states have a natural interpretation as excitations in the flat directions of the matrix model potential.

Convergence analysis of the iterative methods for quasi complementarity problems
International Journal of Mathematics and Mathematical Sciences, Volume 11, Issue 2, Page 319-334, 1988., 1988 In this paper, we consider the iterative methods for the quasi complementarity problems of the form where m is a point‐to‐point mapping and T is a continuous mapping from Rn into itself. The algorithms considered in this paper are general and unified ones, which include many existing algorithms as special cases for solving the complementarity problems.

Holographic description of M-branes via AdS2
Journal of High Energy Physics, 2020 We study AdS2 × S 4 × S 2 × Σ2 solutions in type IIB string theory arising from D1-D3-NS5 brane intersections. These backgrounds enjoy sixteen supercharges and the corresponding internal geometry is non-compact due to the specific form of the warping w.r.
