Download file to see previous pages A reflection group is a distinct group produced by multiple reflections of a finite-dimensional (Euclidean) space. Weyl groups of simple Lie algebras and symmetry groups of regular polytypes are examples of finite reflection groups while infinite groups comprise the Weyl groups of infinite-dimensional Kac–Moody algebras and the triangle groups similar to ordinary tessellations of the hyperbolic plane and Euclidean plane. With regard to symmetry, discrete isometry groups of broad Riemannian manifolds that are formed by reflections are grouped into classes leading to hyperbolic reflection groups (corresponding to hyperbolic space), affine (corresponding to Euclidean space) and finite reflection groups (then-sphere). Coxeter groups are reflection groups that are finitely generated. Unlike reflection groups, Coxeter groups are abstract groups that have a certain structure generated by reflections. An investigation of the topology and geometry of reflection groups will help us comprehend the theoretic properties of the group.
The concept of reflection in a Euclidean space and the hypothesis of discrete groups of motions resulting from reflections has its origin in the study of space polyhedral and plane regular polygons that goes back to early mathematics. In the present day, reflection groups are common in many areas of mathematical research, and geometers encounter them as special convex polytopes or discrete groups of isometries of Riemannian spaces with even curvature. On the other hand, an algebraist encounters reflection groups in group theory, particularly in the representation theory, Coxeter groups and invariant theory. Other areas of mathematics where they may be encountered include the theory of arrangements of hyperplanes, a theory of combinations and permutation, a theory of modular forms and quadratic forms, low-dimensional topology, singularity theory, and the theory of hyperbolic real and complex manifolds (Yau 1986).   ...Download file to see next pagesRead More

The History of Projective Geometry

...of the of the Concerned 2 May The History of Projective Geometry Introduction Projective geometry is the aspects of mathematical studies that had to do with the study of relationships existing between geometric figures and the mappings or images that are brought into existence as a result of the projection of these geometric figures on some other surface. The focus of the projective geometry is the geometric aspects and properties that are affiliated to changes of perspectives. To put it in simple words, projective geometry delves on geometrical aspects like concurrence and co- linearity and ignores properties like distances and angles. In the everyday life, one often...

College Geometry - neutral geometry and Euclidean geometry Euclidean geometry, the parallel postulate when extended makes a three sided diagram that is interior angles sum up to 1800. This is because the subsequent angles are reflections of the points of origin (Eves, 1990). (a) (c) (b) From the diagram above, we can prove that the exterior angle at (a) is equal to the summation of interior angle (b) and (c). The interior angle at pint (a) thus sums up to 180 with the other two angles; (b) and (c). Existence of rectangles in reference to hyperbolic theorem Interior angles in a rectangle add up to 360 degrees. Opposite angles are equal and parallel thus making the figure have four opposite right angles. This is because the base length is a hyperbola and hardly...

Comparison and Analysis of Architects: Le Corbousier and Leon Krior

...(1984), Leon Krier is an architect which conceives of cities as a whole, and that his buildings are conceived to be part of the larger whole. He needs to conceptualize the town or the city when he designs his buildings, because simply constructing a disembodied part of the city – a building - is not of an interest to him. This, according to Porphyrios, makes Krier a “heterosexual. All his single buildings have real or implied partners” (Pophyrios, 1984, p. 12). Or, as Pophyrios, his buildings belong to larger groups, and these groups and families are conceived as being a part of the need of the society to which they serve. In this way, Krier is not narcissistic. His buildings are not...

Fractal Geometry

...Fractal Geometry Fractal geometry is rather new mathematical theory which is completely different from the traditional concepts of Euclidean Geometry. Fractal geometry describes elf-similar or scale symmetric objects. It means that if to magnify these objects, their parts will bear an exact resemblance to the whole object. The word "fractal" was created by Benoit Mandelbrot and it means "to break", whereas the form of adjective "fractus" means "fragmentated". (Brandt 24) It is a matter of fact that the word "fractal" has two definite meanings: the first meaning refer to colloquial use and the second is connected with geometry. In colloquial speech fractal...

Key definitions To make our considerations of extensions of the Euler's theorem and triangulation concepts more pure, we need to preliminary define the key notions from the related topics. First of all, polygon is a closed plane figure with sides (Weisstein 2002). Then, a polyhedron is the union of a finite set of polygons such that: (i) any pair of polygons meets only at their sides or corners; (ii) each side of each polygon meets exactly one other polygon along an edge; (iii) it is possible to travel from the interior of any polygon to the...

...Geometry Geometry is a branch of mathematics that deals or attempts to explain and describe the shape, size, or relative position of an object in space. The study of geometry dates back to the time of ancient Greek. The Euclidian geometry for example originated in the 6th century and it laid the foundation for modern geometry. Currently, the study has advanced to include other branches of mathematics such as number theory, algebra, and topology. Riemannian geometry for example is among the latest braches of geometry. Each of the above fields of specialization has a different approach to the study of geometry (Mlodinow, 2002). Indeed, a good mathematician will view the different branches of geometry as mere tools designed to enable... ...

...Step Draw a line AB that we will be divided into 3 (in this case) equal parts. From point A, draw a line segment at an angle to the given line, and about the same length. The exact length is not important. Set the compasses on A, and set its width to a bit less than one third of the length of the new line. Step the compasses along the line, marking off 3 arcs. Label the last one C. With the compasses width set to CB, draw an arc from A just below it. With the compasses width set to AC, draw an arc from B crossing the one drawn in step 4. This intersection is point D. Draw a line from D to B. Using the same compasses width as used to step along AC, step the compasses from D along DB making 3 new arcs across the line Draw lines...
