Open-closed homotopy algebra in mathematical physics [PDF]
, 2005 In this paper we discuss various aspects of open-closed homotopy algebras (OCHAs) presented in our previous paper, inspired by Zwiebach's open-closed string field theory, but that first paper concentrated on the mathematical aspects.

Understanding student use of differentials in physics integration problems
Physical Review Special Topics. Physics Education Research, 2013 This study focuses on students’ use of the mathematical concept of differentials in physics problem solving. For instance, in electrostatics, students need to set up an integral to find the electric field due to a charged bar, an activity that involves ...

On the Mathematics of Coframe Formalism and Einstein–Cartan Theory—A Brief Review
Universe, 2019 This article is a review of what could be considered the basic mathematics of Einstein−Cartan theory. We discuss the formalism of principal bundles, principal connections, curvature forms, gauge fields, torsion form, and Bianchi identities, and ...

Negative flows and non-autonomous reductions of the Volterra lattice [PDF]
Open Communications in Nonlinear Mathematical PhysicsWe study reductions of the Volterra lattice corresponding to stationary equations for the additional, noncommutative subalgebra of symmetries. It is shown that, in the case of general position, such a reduction is equivalent to the stationary equation ...

FEBS Open Bio, EarlyView.The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

Soliton equations: admitted solutions and invariances via B\"acklund transformations [PDF]
Open Communications in Nonlinear Mathematical PhysicsA couple of applications of B\"acklund transformations in the study of nonlinear evolution equations is here given. Specifically, we are concerned about third order nonlinear evolution equations.

Wavelets in mathematical physics: q-oscillators
, 2003 We construct representations of a q-oscillator algebra by operators on Fock space on positive matrices. They emerge from a multiresolution scaling construction used in wavelet analysis.
