Lagrange’s equations in nonholonomic mechanics [PDF]
Nelineinaya Dinamika, 2013 Summary: The question on possibility of writing the equations of motion of a nonholonomic system in the form of Lagrange's equations of the 2nd kind for the minimal number of parameters is considered. The corresponding results of \textit{J. Hadamard} [Bordeaux Mém. (4) V. 397--417 (1895; JFM 26.0849.02)] and \textit{H. Béghin} [Bull. Soc. Math. Fr. 57,

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

The Schwarzian derivative and Euler–Lagrange equations
Journal of Geometry and Physics, 2022 We study the Schwarzian derivative from a variational viewpoint. Firstly we show that the Schwarzian derivative defines a first integral of the Euler--Lagrange equation of a second order Lagrangian. Secondly, we show that the Schwarzian derivative itself is the Euler--Lagrange operator for an appropriately chosen class of variations.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Resonance in the Cart-Pendulum System—An Asymptotic Approach
Applied Sciences, 2021 The major objective of this research is to study the planar dynamical motion of 2DOF of an auto-parametric pendulum attached with a damped system. Using Lagrange’s equations in terms of generalized coordinates, the fundamental equations of motion (EOM ...

On the validity of the Euler–Lagrange equation
Journal of Mathematical Analysis and Applications, 2005 The authors deal with the variational problem \[ J(x)=\int^b_aL\bigl (t,x(t),x'(t)\bigr)\,dt\to\min\quad \bigl(x(a)=A,x(b)=B\bigr) \] in the space \(M\) of absolutely continuous vector-valued functions \(x(t)\in \mathbb{R}^n\) \((a\leq t\leq b)\). Let \(\widehat x(t)\) be a local weak minimizer. Assumptions: (i) \(\nabla_xL(.,\widehat x(.),\widehat x'(.

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics
