International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...

Left-invariant Hermitian connections on Lie groups with almost Hermitian structures
Glasnik MatematickiLeft-invariant Hermitian and Gauduchon connections are studied on an arbitrary Lie group \(G\) equipped with an arbitrary left-invariant almost Hermitian structure \((\langle\cdot,\cdot\rangle,J)\). The space of left-invariant Hermitian connections is shown to be in one-to-one correspondence with the space \(\wedge^{(1,1)}\mathfrak{g}^\ast\otimes ...

Almost Hermitian Structures From Almost Contact Metric Manifolds and Their Curvature Properties
, 2023 In this manuscript, we consider almost Hermitian manifolds and almost contact metric manifolds. We construct almost Hermitian manifolds from the product of almost contact metric manifolds with R by warped product. Depending on the function of warped product, we investigate the curvature properties of the almost Hermitian manifolds obtained in this way.

Remarks on some almost Hermitian structure on the tangent bundle. II
, 2014 Let \(M\) and \(TM\) be an almost Hermitian manifold and its tangent bundle respectively. \textit{M. Tahara} et al. [Note Mat. 18, No. 1, 131--141 (1998; Zbl 0964.53021)] constructed three almost complex structures \(J_1,J_2,J_3\) on \(TM\), which define in special cases an almost hyper-complex structure.
