"Jabberwocky" is a nonsense poem written by Lewis Carroll about the killing of a creature named "the Jabberwock". It was included in his 1871 novel Through the Looking-Glass , the sequel to Alice's Adventures in Wonderland (1865).
In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measurement (such as metres and grams) and tracking these dimensions as calculations or comparisons are performed.

For example, in the scale (and conformally) invariant theory describing the critical points of the two-dimensional Ising model there is an operator whose dimension is 1/8. [2] [1] Operator multiplication is subtle in interacting theories compared to free theories.
Infinite Dimensional Analysis, Quantum Probability and Related Topics is a quarterly peer-reviewed scientific journal published since 1998 by World Scientific. It covers the development of infinite dimensional analysis , quantum probability , and their applications to classical probability and other areas of physics .
It is closely related to dimensional analysis. In some physical systems, the term scaling is used interchangeably with nondimensionalization, in order to suggest that certain quantities are better measured relative to some appropriate unit. These units refer to quantities intrinsic to the system, rather than units such as SI units.
A failed attempt to comb a hairy 3-ball (2-sphere), leaving a tuft at each pole A hairy doughnut (2-torus), on the other hand, is quite easily combable. A continuous tangent vector field on a 2-sphere with only one pole, in this case a dipole field with index 2.
Geometric analysis also includes global analysis, which concerns the study of differential equations on manifolds, and the relationship between differential equations and topology. The following is a partial list of major topics within geometric analysis: Gauge theory; Harmonic maps; Kähler–Einstein metrics; Mean curvature flow; Minimal ...
