Higher-Order Orderings for Normal Rewriting [PDF]
, 2006 We extend the termination proof methods based on reduction orderings to higher-order rewriting systems a la Nipkow using higher-order pattern matching for firing rules, and accommodate for any use of eta, as a reduction, as an expansion or as an equation.

Operator ordering and causality
, 2011 It is shown that causality violations [M. de Haan, Physica 132A, 375, 397 (1985)], emerging when the conventional definition of the time-normal operator ordering [P.L.Kelley and W.H.Kleiner, Phys.Rev.

Wick's Theorem for non-symmetric normal ordered products and contractions [PDF]
, 1998 We consider arbitrary splits of field operators into two parts, and use the corresponding definition of normal ordering introduced by Evans and Steer. In this case the normal ordered products and contractions have none of the special symmetry properties ...

Combinatorial approach to generalized Bell and Stirling numbers and boson normal ordering problem
, 2005 We consider the numbers arising in the problem of normal ordering of expressions in canonical boson creation and annihilation operators. We treat a general form of a boson string which is shown to be associated with generalizations of Stirling and Bell ...

Phase space path integral in curved space [PDF]
, 2000 Phase space path integral is worked out in a riemannian geometry, by employing a prescription for the infinitesimal propagator that takes riemannian normal coordinates and momenta on an equal footing.

Poisson brackets of normal-ordered Wilson loops [PDF]
Journal of Mathematical Physics, 1999 We formulate Yang–Mills theory in terms of the large-N limit, viewed as a classical limit, of gauge-invariant dynamical variables, which are closely related to Wilson loops, via deformation quantization. We obtain a Poisson algebra of these dynamical variables corresponding to normal-ordered quantum (at a finite value of ℏ) operators.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

Advances in High Energy Physics, 2023 We analyze the radiative stability of the next-to-tribimaximal mixings (NTBM) with the variation of the SUSY breaking scale (mS) in MSSM, for both normal ordering (NO) and inverted ordering (IO) at the fixed input value of the seesaw scale MR=1015 GeV ...
