Diagonal Line A diagonal line connects two points in a polygon that are otherwise not connected. For instance, a diagonal will connect opposite corners of a square that are otherwise separated by another point. In geometry, lines continue forever in both directions; because a diagonal line is co...

For solutions with a planar symmetry (or a flat horizon), one can naturally use Cartesian coordinates on the horizon. In this case, we show that the presence of matter is required for existence of non-trivial solutions. This is a novel and very interesting feature of these constructions. We...
For a symmetric matrix, the valuable property of symmetry will be preserved if identical permutations are used for both the rows and the columns. Algorithms for bandwidth reduction are discussed in Chapter 4. When a system of linear equations has a banded matrix of coefficients and the system ...
These results are developed in part using properties of the Perron complement of nonnegative matrices, and the concept of line-sum symmetry. Some results apply to general essentially-nonnegative matrices, while others are specialized for sub-classes (e.g., diagonally-symmetrizable, or having a ...
cutting lines of diagonal cuts at two ends can be in parallel or axial symmetry, angle of the diagonal cutting can be changed according to actual demands, and therefore, the diagonal cut pipe can save raw materials, increases utilization rate of the raw materials, reduces production cost and ...
