The noncovariant gauges in 3-form theories
, 2013 We study the 3-form gauge theory in the context of generalized BRST formulation. We construct the finite field-dependent BRST (FFBRST) symmetry for such a theory.

New Relations for Gauge-Theory Amplitudes [PDF]
, 2008 We present an identity satisfied by the kinematic factors of diagrams describing the tree amplitudes of massless gauge theories. This identity is a kinematic analog of the Jacobi identity for color factors.

Macroscopic strings as heavy quarks: Large-N gauge theory and anti-de Sitter supergravity [PDF]
, 1998 . We study some aspects of Maldacena's large-N correspondence between ${\cal N}=4$ superconformal gauge theory on the D3-brane and maximal supergravity on AdS$_5 \times S_5$ by introducing macroscopic strings as heavy (anti-) quark probes.

Gauge Freedom in Path Integrals in Abelian Gauge Theory
, 2015 We extend gauge symmetry of Abelian gauge field to incorporate quantum gauge degrees of freedom. We twice apply the Harada--Tsutsui gauge recovery procedure to gauge-fixed theories.

Entropy, 2016 We introduce the symplectic structure of information geometry based on Souriau’s Lie group thermodynamics model, with a covariant definition of Gibbs equilibrium via invariances through co-adjoint action of a group on its moment space, defining physical ...

M2-brane surface operators and gauge theory dualities in Toda [PDF]
, 2014 A bstractWe give a microscopic two dimensional N$$ \mathcal{N} $$ = (2, 2) gauge theory description of arbitrary M2-branes ending on Nf M5-branes wrapping a punctured Riemann surface. These realize surface operators in four dimensional N$$ \mathcal{N} $$

Canonical Gauges in Higher Gauge Theory [PDF]
Communications in Mathematical Physics, 2019 We study the problem of finding good gauges for connections in higher gauge theories. We find that, for $2$-connections in strict $2$-gauge theory and $3$-connections in $3$-gauge theory, there are local "Coulomb gauges" that are more canonical than in classical gauge theory.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

On Nonlinear Gauge Theory from a Deformation Theory Perspective [PDF]
, 1999 Nonlinear gauge theory is a gauge theory based on a nonlinear Lie algebra (finite W algebra) or a Poisson algebra, which yields a canonical star product for deformation quantization as a correlator on a disk.

Consistent Treatment of Quantum Systems with a Time-Dependent Hilbert Space
EntropyWe consider some basic problems associated with quantum mechanics of systems having a time-dependent Hilbert space. We provide a consistent treatment of these systems and address the possibility of describing them in terms of a time-independent Hilbert ...
