Low dimensional topology normally refers to either 3 or 4 dimensional topology, and the techniques are quite different in each of these dimensions. I have studied some knot theory notes and I like the subject matter. So I would firstly like to study about every sub-field of low dimensional topology.

Right now I am studying Topology by Munkres. I would like to know how I should proceed towards specialising in a sub-field in low dimensional topology. Freedman and Quinn's book is also good. Hempel and Jaco have both written classic texts on 3-manifold theory.
Thurston's book "The geometry and topology of 3-manifolds" is also quite good. Drouglas Crash Drouglas Crash 6 6 bronze badges.
Some complex networks are characterized by fractal dimensions. Science fiction texts often mention the concept of "dimension" when referring to parallel or alternate universes or other imagined planes of existence. One of the most heralded science fiction stories regarding true geometric dimensionality, and often recommended as a starting point for those just starting to investigate such matters, is the novella Flatland by Edwin A. Isaac Asimov, in his foreword to the Signet Classics edition, described Flatland as "The best introduction one can find into the manner of perceiving dimensions.
The idea of other dimensions was incorporated into many early science fiction stories, appearing prominently, for example, in Miles J. Classic stories involving other dimensions include Robert A. Heinlein 's —And He Built a Crooked House , in which a California architect designs a house based on a three-dimensional projection of a tesseract; and Alan E. Another reference is Madeleine L'Engle 's novel A Wrinkle In Time , which uses the fifth dimension as a way for "tesseracting the universe" or "folding" space in order to move across it quickly. Immanuel Kant , in , wrote: "That everywhere space which is not itself the boundary of another space has three dimensions and that space in general cannot have more dimensions is based on the proposition that not more than three lines can intersect at right angles in one point.
This proposition cannot at all be shown from concepts, but rests immediately on intuition and indeed on pure intuition a priori because it is apodictically demonstrably certain. The protagonist in the tale is a shadow who is aware of and able to communicate with other shadows, but who is trapped on a two-dimensional surface. According to Fechner, this "shadow-man" would conceive of the third dimension as being one of time.
From Wikipedia, the free encyclopedia. This article is about the dimension of a space. For the dimension of an object, see size. For the dimension of a quantity, see Dimensional analysis.

This book develops some of the extraordinary richness, beauty, and power of geometry in two and three dimensions, and the strong connection of geometry with topology. Hyperbolic geometry is the star. A strong effort has been made to convey not just denatured formal reasoning definitions, theorems, and proofs , but a living feeling for the subject.
There are many figures, examples, and exercises of varying difficulty. This book was the origin of a grand scheme developed by Thurston that is now coming to fruition. In the s and s the mathematics of two-dimensional spaces was formalized. It was Thurston's goal to do the same for three-dimensional spaces. To do this, he had to establish the strong connection of geometry to topology--the study of qualitative questions about geometrical structures. The author created a new set of concepts, and the expression "Thurston-type geometry" has become a commonplace.
