    Series Summation
AI Thread Summary
The discussion focuses on finding a symbol for a vector of observations that avoids implying multiplication or summation, specifically for expressing inequalities among means of genotypes. The user seeks clarification on whether the symbol Pi is appropriate for this purpose. There is a suggestion that the notation could be represented as a series of inequalities between different genotype means. Additionally, guidance is provided on how to format mathematical expressions using LaTeX. The conversation emphasizes the need for clarity in representing statistical relationships without ambiguity.

Hi. I'm sorry to bother you, but I was trying to find the symbol used for a vector of observations that doesn't implicitly infre multiplication or summation. I'm trying to express an inequality at the simple and general levels so that

\muAa \ne \muAA, \muaa

The idea is that this inequality should apply to means for factors (genotypes) at a single effect (a gene in this case), and more generally to the system of all means for all factors at all effects. Is that Pi that I should be using? I can't remember and can't find it.

I don't quite understand you. Are you simply trying to say that one vector of observations does not equal another?
In that case, it would be $$(\mu_{Aa_1},\mu_{Aa_2},\mu_{Aa_3}...) \neq (\mu_{AA_1}...) \neq ...$$
Can you elaborate a little more on what you need?
Also, to type $\LaTeX$, use \$ and \$$ symbols or $$[\MATH] tags.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
