A contribution to the theory of the extended Lagrangian formalism for rheonomic systems [PDF]
Theoretical and Applied Mechanics, 2009 In this paper the generalization of the notion of variation in the extended Lagrangian formalism for the rheonomic mechanical systems (Đ. Mušicki, 2004) is formulated and analyzed in details.

A note on broken dilatation symmetry in planar noncommutative theory
Nuclear Physics B, 2021 A riveting study of Ward-Takahashi identities is presented for a broken dilatation or scale symmetry in a generalized quantum Hall system. On using the “Peierls substitution” scheme, it is shown that noncommutativity between spatial coordinates emerges ...

Multi-block technique applied to Navier-Stokes equations in two dimensions
Semina: Ciências Exatas e Tecnológicas, 2018 In this work, numerical solutions of the two-dimensional Navier-Stokes and Euler equations using explicit MacCormack method on multi-block structured mesh are presented for steady state and unsteady state compressible fluid flows.

Generalized transformations and coordinates for static spherically symmetric general relativity [PDF]
Royal Society Open Science, 2018 We examine a static, spherically symmetric solution of the empty space field equations of general relativity with a non-orthogonal line element which gives rise to an opportunity that does not occur in the standard derivations of the Schwarzschild ...

Ladder Operators for the Spherical 3D Harmonic Oscillator [PDF]
Revista Brasileira de Ensino de Física, 2020 The Schrödinger equation for an isotropic three-dimensional harmonic oscillator is solved using ladder operators. The starting point is the shape invariance condition, obtained from supersymmetric quantum mechanics.

Generalized harmonic spatial coordinates and hyperbolic shift conditions [PDF]
, 2005 We propose a generalization of the condition for harmonic spatial coordinates analogous to the generalization of the harmonic time slices introduced by Bona et al., and closely related to dynamic shift conditions recently proposed by Lindblom and Scheel,

Some New Estimates on Coordinates of Generalized Convex Interval-Valued Functions
Fractal and Fractional, 2022 The theory of convex and nonconvex mapping has a lot of applications in the field of applied mathematics and engineering. The Riemann integrals are the most significant operator of interval theory, which permits the generalization of the classical theory

Tensor Hierarchy and Generalized Cartan Calculus in SL(3)$\times$SL(2) Exceptional Field Theory [PDF]
, 2015 We construct exceptional field theory for the duality group SL(3)$\times$SL(2). The theory is defined on a space with 8 `external' coordinates and 6 `internal' coordinates in the $(3,2)$ fundamental representation, leading to a 14-dimensional generalized
