Correspondences and the Theory of Groups [PDF]
Transactions of the American Mathematical Society, 1906 The object of this paper is to bring together several points connected with the general theory of correspondences and continuous groups, and to apply them to the theory of screws. Although the several results are in general not new, it seems of interest to give the accompanying presentation of the subject, as it furnishes an excellent examiple of the ...

The R *-operation for Feynman graphs with generic numerators
Journal of High Energy Physics, 2017 The R *-operation by Chetyrkin, Tkachov, and Smirnov is a generalisation of the BPHZ R-operation, which subtracts both ultraviolet and infrared divergences of euclidean Feynman graphs with non-exceptional external momenta.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

How tropical are seven- and eight-particle amplitudes?
Journal of High Energy Physics, 2020 We study tropical Grassmanians Tr(k, n) in relation to cluster algebras, and assess their applicability to n-particle amplitudes for n = 7, 8. In N $$ \mathcal{N} $$ = 4 super Yang-Mills theory, we first show that while the totally positive part of Tr(4,

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

Overlap singularity and time evolution in integrable quantum field theory
Journal of High Energy Physics, 2018 We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude necessarily has a singularity at the two-particle threshold.

Gaudin models and multipoint conformal blocks III: comb channel coordinates and OPE factorisation
Journal of High Energy Physics, 2022 We continue the exploration of multipoint scalar comb channel blocks for conformal field theories in 3D and 4D. The central goal here is to construct novel comb channel cross ratios that are well adapted to perform projections onto all intermediate ...

“Nondualism is philosophy, not ethnography”: A review of the 2011 GDAT debate
, 2012 The motion for the 2011 Group Debate in Anthropological Theory (GDAT), which took place at the University of Manchester (on November 12, 2011) was “Nondualism is philosophy, not ethnography”. Nondualism as a philosophical term entails continuity between

MORITA'S THEORY FOR THE SYMPLECTIC GROUPS [PDF]
International Journal of Number Theory, 2011 We construct and study the holomorphic discrete series representations and the principal series representations of the symplectic group Sp (2n, F) over a p-adic field F as well as a duality between some sub-representations of these two representations. The constructions of these two representations generalize those defined in Morita and Murase's works.
