Manipulation of Rangeland Wildlife Habitatstwo decades, both from the fields of mathematics and economics. The purpose of this work is to provide a comprehensive survey on the properties of the homogeneous and quasi-homogeneous production models, most of these properties being of geometric nature and obtained using a differential geometric t暴发户 发表于 2025-3-31 02:16:32

Rangeland Stewardship in Central AsiaThe paper is devoted to study of rotary mappings equations of two-dimensional equidistant (pseudo-) Riemannian spaces. The general solution of these equations is found beyond these spaces under minimal requirements for the differentiability of the studied objects.AORTA 发表于 2025-3-31 20:18:17

We survey recent progress in this topic.Choreography 发表于 2025-4-1 00:56:37
On General Solutions of Sinyukov Equations on Two-Dimensional Equidistant (pseudo-)Riemannian SpaceThe paper is devoted to study of Sinyukov equations on two-dimensional equidistant (pseudo-) Riemannian spaces. The general solution of Sinyukov equations is found beyond these spaces under minimal requirements for the differentiability of the studied objects.
