JMP: Comments and Errata

On the variational homotopy perturbation method for nonlinear oscillators

Francisco M. Fernandez
In this paper, I discuss a recent application of a variational homotopy perturbation method to rather simple nonlinear oscillators. It is shown that the main equations are inconsistent and for that reason the results may be of scarce utility. ... [J. Math. Phys. 53, 024101 (2012)] published Tue Feb 7, 2012.

F. Haas
We show that Theorems 8, 9, and 11 in the work cited in the title are incorrect in general. The existence of globally well-defined first integrals or flow invariant functions for dynamical systems in R cannot be taken for granted. ... [J. Math. Phys. 52, 124101 (2011)] published Mon Dec 5, 2011.

Comment on Coherent states on spheres [J. Math. Phys. 43, 1211 (2002)]

A. Rabeie and Z. Jalilian
Hall and Mitchell described a family of heat kernels (or equivalently coherent states) and an associated resolution of the identity for a quantum particle whose classical configuration space is the d-dimensional sphere S J. Math. Phys. 43(3), 1211 (2002). These heat kernels were chosen intelligently ... [J. Math. Phys. 52, 084101 (2011)] published Mon Aug 29, 2011.

In this note we correct a mistake made in my paper [J. Math. Phys. 51, 033506 (2010)]. Using the contour integration method we shall obtain a new regularized trace formula for Schrodinger operator with energy-dependent potential. ... [J. Math. Phys. 52, 049902 (2011)] published Thu Apr 28, 2011.

Hai-Jun Wang
In a recent paper [H.-J. Wang, J. Math. Phys. 49, 033513 (2008)] a complex-geometry model was proposed to interpret the interaction of electromagnetism and the interaction between quarks while the nonlocal effects are involved. In that theoretical frame, from the metric matrix one can obtain a deter ... [J. Math. Phys. 51, 054102 (2010)] published Fri May 14, 2010.

Comment on Functional determinants in higher derivative Lagrangian theories [J. Math. Phys. 50, 103517 (2009)]

We comment on the recent paper of Di Criscienzo and Zerbini [J. Math. Phys. 50, 103517 (2009)]. We argue that the Euclidean evolution operator computed in our paper (K. Andrzejewski et al., e-print arXiv:0904.3055) is correct contrary to the claim of Di Criscienzo and Zerbini. ... [J. Math. Phys. 51, 054101 (2010)] published Thu May 6, 2010.
