Hamilton-Pontryagin Integrators on Lie Groups [PDF]
, 2007 In this thesis structure-preserving time integrators for mechanical systems whose configuration space is a Lie group are derived from a Hamilton-Pontryagin (HP) variational principle.

The Long Shadow of Karl Weierstraß Over the Calculus of Variations
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.

Estimating Euler equations [PDF]
In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of preference parameters.

Mathematical Geography in the Eighteenth Century: Euler, Lagrange and Lambert [PDF]
Modern mathematicians rarely consult eighteenth-century sources directly. Language barriers, obsolete notation, and dispersed arguments make such texts seem more cumbersome than enlightening, especially when contemporary expositions offer streamlined ...

Stability of a generalized Euler–Lagrange radical multifarious functional equation
In this paper, we introduce a new generalized version of the Euler–Lagrange functional equation, namely, generalized Euler–Lagrange radical multifarious functional equation and investigate its Hyers–Ulam stability in fuzzy modular spaces (in short, FM ...

Topology, Orientation and Fiber Path Optimization for Layered Anisotropic Materials
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Topology optimization and additive manufacturing complement each other: the freedom offered by design optimization enables the creation of complex, highly efficient structures that are often feasible only with additive manufacturing. However, most structural optimization methods assume isotropic material properties, an assumption that ...

On the Computation of Crack Surface Normals in the Phase‐Field Model of Hydraulic Fracture
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Hydraulic fracturing techniques have been used to extract oil from the Earth's crust and to enhance the efficiency of geothermal systems among other applications. Numerical simulation of hydraulic fracturing is essential for predicting the environmental impact of this method, as well as its efficiency in such applications. In the present work,

Euler, Lagrange and life insurance
, 2008 Frederick the Great, who had summoned Euler from St. Petersburg to Berlin to organize the Academy of Science, often asked his advise on technical matters concerning pension funds or life annuities, even if Euler’s memoirs on this theme were all published
