Is it possible to have a dimension that is not an integer?

Is it possible to have a dimension that is not an integer?

If you take a two-dimensional object in a three-dimensional ambient space (say, a piece of paper) and scale it up, then its area will increase by a factor of s2. This number in the exponent is basically the fractal dimension of that object, and it’s possible for it to be non-integral.

What do you mean by fractal dimension?

In mathematics, more specifically in fractal geometry, a fractal dimension is a ratio providing a statistical index of complexity comparing how detail in a pattern (strictly speaking, a fractal pattern) changes with the scale at which it is measured.

What is the hausdorff method?

The Hausdorff dimension measures the local size of a space taking into account the distance between points, the metric. Consider the number N(r) of balls of radius at most r required to cover X completely. When r is very small, N(r) grows polynomially with 1/r.

How is Hausdorff dimension calculated?

The Hausdorff Dimension We consider N=rD, take the log of both sides, and get log(N) = D log(r). If we solve for D. D = log(N)/log(r) The point: examined this way, D need not be an integer, as it is in Euclidean geometry. It could be a fraction, as it is in fractal geometry.

Are there negative dimensions?

Dimension of a (finite dimensional) vector space is defined as the cardinality of a basis for the vector space. Since the cardinality cannot be negative, negative dimension for vector spaces is meaningless.

What is meant by topological dimension?

The topological dimension \dim (X) is also called the Čech-Lebesgue covering dimension , or simply the Lebesgue dimension , of X. It is clear from its definition that topological dimension is a topological invariant, that is, one has \dim (X) = \dim (Y) whenever X and Y are homeomorphic topological spaces.

What is the Hausdorff dimension of the set of natural numbers?

Then the set ^Y*A of numbers which are normal to every base from R and to no base from S has Hausdorff dimension at least log (A – l)/log A. 2.

What is Hausdorff dimension used for?

Hausdorff measure takes the idea of looking at the volume of coverings by rectangles and generalizes it to arbitrary metric spaces and fractional α.

What is the meaning of negative dimension?

For a dimension to be negative it would need a value of quality to the opposite, which do not appear to exist. The distance between two points exists or not, the distance is a positive numerical expression, a distance between two points does appear to be able to be negative.

What is a zero dimensional object?

Zero Dimensions: A point has zero dimensions. There’s no length, height, width, or volume. Its only property is its location. You could have a collection of points, such as the endpoints of a line or the corners of a square, but it would still be a zero-dimensional object.

What is the topological dimension of Koch curve?

Therefore for koch curve topological dimension is 1 but fractal dimension is 1.2618.
