| 21. | A lattice triangle is any triangle drawn within a 2D lattice such that all vertices lie on lattice points.
|
| 22. | If a displacement exists between any two lattice points, then that same displacement is repeated everywhere in the lattice.
|
| 23. | Locate a primitive unit cell of the FCC, i . e ., a unit cell with one lattice point.
|
| 24. | Consider an angle ? such that a rotation of angle ? about any lattice point is a symmetry of the lattice.
|
| 25. | If the collection of lattice points " A " generates the character lattice, this variety is a torus embedding.
|
| 26. | A Wigner Seitz cell is an example of a primitive cell, which is a unit cell containing exactly one lattice point.
|
| 27. | The same recurrence relation is applied at each lattice point, although the parameter r is slightly increased with each time step.
|
| 28. | It is the locus of points in space that are closer to that lattice point than to any of the other lattice points.
|
| 29. | It is the locus of points in space that are closer to that lattice point than to any of the other lattice points.
|
| 30. | His main area of work was in number theory and mathematical analysis; he proved a number of results on lattice point problems.
