A more "complete" version of the Pi-theorem: DRAFT
- Mathematics
- 2011
The traditional Pi-theorem tells us that for any dimensionally invariant relation there exists a full set of independent dimensionless "Pi groups" which can be used to nondimensionalise the relation.…
On Buckingham's $\Pi$-Theorem
- Mathematics
- 2019
Roughly speaking, Buckingham's $\Pi$-Theorem provides a method to "guess" the structure of physical formulas simply by studying the dimensions (the physical units) of the involved quantities. Here we…
On the proof of the Π-theorem in dimension theory
- Physics
- 2006
The 100-year anniversary of the proof of one of the brightest and most universal theorems in mechanics and physics, the Π-theorem in dimension theory is approaching. In connection with this…
Dimensional Analysis of Matrices State-Space Models and Dimensionless Units [Lecture Notes]
- MathematicsIEEE Control Systems
- 2007
Physical dimensions and units, such as mass (kg), length (m), time (s), and charge (C), provide the link between mathematics and the physical world. It is well known that careful attention to…
What Are the Physical Dimensions of the A Matrix?
- Mathematics2007 American Control Conference
- 2007
This article extended results of the work of Hart (1995) by determining the dimensional structure of a matrix under which standard operations involving the inverse, powers, exponential, and eigenvalues are valid.
Weak Solutions, A Priori Estimates
- Mathematics
- 2017
The fundamental laws of continuum mechanics that can be interpreted as infinite families of integral identities equivalent to systems of partial differential equations give rise to the concept of…
Practical Guide to the Symbolic Computation of Symmetries of Differential Equations
- Mathematics, Computer Science
- 2014
A computational approach to finding symmetries and computer algebra programs to compute the usually very large system of determining partial differential equations and a computer algebra algorithm that at least automatically solves most of these equations and in simple cases provides a complete solution.
The Amazing Power of Dimensional Analysis: Quantifying Market Impact
- Economics
- 2017
This note complements the inspiring work on dimensional analysis and market microstructure by Kyle and Obizhaeva [18]. Following closely these authors, our main result shows by a similar argument as…
Dynamic Dimensional Analysis
- Computer Science
- 2020
This chapter develops the concept of dimensional analysis to be used in model-prototype similarities, nondimensionalization, and simplification of equations for the most general coverage. The goals…
