Symmetry Classification of First Integrals for Scalar Linearizable Second-Order ODEs

open access: yesJournal of Applied Mathematics, 2012
Symmetries of the fundamental first integrals for scalar second-order ordinary differential equations (ODEs) which are linear or linearizable by point transformations have already been obtained.

Quantification and Negation in Event Semantics

open access: yesThe Baltic International Yearbook of Cognition, Logic and Communication, 2010
Recently, it has been claimed that event semantics does not go well together with quantification, especially if one rejects syntactic, LF-based approaches to quantifier scope.

The CEGM NLSM

open access: yesJournal of High Energy Physics
Studying quantum field theories through geometric principles has revealed deep connections between physics and mathematics, including the discovery by Cachazo, Early, Guevara and Mizera (CEGM) of a generalization of biadjoint scalar amplitudes.

Relativistic shifted-l expansion technique for Dirac and Klein-Gordon equations [PDF]

open access: yesCommun. Theor. Phys. 29 (1998) 587-594, 1999
The shifted-i expansion technique (SLET) is extended to solve for Dirac particle trapped in spherically symmetric scalar and/or 4-vector potentials. A parameter {\lambda}=0,1 is introduced in such a way that one can obtain the Klein-Gordon (KG) bound states from Dirac bound states.
