Hamilton-Jacobi approach for first order actions and theories with higher derivatives
(Academic Press Inc. Elsevier B.V., 2008-03-01)
In this work, we analyze systems described by Lagrangians with higher order derivatives in the context of the Hamilton-Jacobi formalism for first order actions. Two different approaches are studied here: the first one is ...

Higher-order theories from the minimal length
(2016-06-10)
We show that the introduction of a minimal length in the context of noncommutative space-time gives rise (after some considerations) to higher-order theories. We then explicitly demonstrate how these higher-derivative ...

LIMITS on THE COUPLING CONSTANT of HIGHER-DERIVATIVE ELECTROMAGNETISM
(World Scientific Publ Co Pte Ltd, 2010-02-10)
We investigate a higher-derivative version of QED constructed by adding to the Maxwell's Lagrangian a term containing second-order derivatives of the electromagnetic potentials. The resulting Lagrangian, besides being gauge ...
Higher derivative massive spin-3 models in D=2+1
(2016-07-26)
We find new higher derivative models describing a parity doublet of massive spin-3 modes in D=2+1 dimensions. One of them is of fourth order in derivatives while the other one is of sixth order. They are complete, in the ...
Chawla-Numerov method revisited
(1991-08-27)
The well-known two-step fourth-order Numerov method was shown to have better interval of periodicity when made explicit, see Chawla (1984). It is readily verifiable that the improved method still has phase-lag of order 4. ...

Second order higher-derivative corrections in Double Field Theory
(Springer, 2017-06)
HSZ Double Field Theory is a higher-derivative theory of gravity with exact and manifest T-duality symmetry. The first order corrections in the massless sector were shown to be governed solely by Chern-Simons deformations ...
Second order gauge theory
(Elsevier B.V., 2007-05-01)
A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength G = partial derivative F + fAF arises besides the one of the first order treatment, ...
