pintaalasäilyttävä
Pintaalasäilyttävä is a Finnish term that translates to "surface area conserving" or "area-preserving" in English. It describes a property of certain mathematical transformations or mappings, particularly in geometry. A transformation is pintaalasäilyttävä if it preserves the area of any shape or region it is applied to. This means that if you have a region with a certain area, and you apply a pintaalasäilyttävä transformation to it, the resulting region will have exactly the same area.
In the context of linear algebra, a linear transformation represented by a matrix is pintaalasäilyttävä if
The concept of pintaalasäilyttävä transformations is important in various fields of mathematics, including differential geometry, where
