@jstac what should referencing look like in the code book?
Should there be a bibliography, links to the articles, no links or should I avoid references?

This book is really fantastic. I would like to translate the code in this book into Wolfram Language/Mathematica and put the Jupyter notebooks in Github. Can I?

E.g., "We begin by loading a NetworkX directed graph object the represents the international trade in crude oil."

When plotting graphs, whether self loops are included depend on the version of NetworkX. The text includes plots both with and without self loops.

Proposed solution: use the later version of networkx that plots self loops but remove the diagonal of the adjacency matrix if they are not wanted.

Preface (page vi)

A verb is missing in the following sentence: "At the end of each chapter we provide notes, where informal comments
and references."

Update figures in

https://networks.quantecon.org/ch_intro.html
https://networks.quantecon.org/ch_production.html

to latest data.

The Chapter 1 code is not compatible with Google Colab as it request access to latex to render some of the network plots.

Thanks to a reader for reporting this issue.

Setup the quantecon_book_networks as a PyPI package to facilitate students building images etc.

We are looking to simplify by:

• remove jupyter-book builds
• add code that is currently in this repo (as the source of truth) and convert them to files as used by the book
• make the code downloadable as a file
• archive quantecon-book-networks

Related code:

export_figures = False

and

if export_figures == True:
	plt.savefig("figures/xx.pdf")

where xx is the figure’s name.

export_figures name lists for each chapter:

Issues with https://quantecon.github.io/book-networks/intro.html

Can we get "and" between the authors instead of a comma? Also, in the title, can we have "Theory and Computation" on a new line?

Don't worry if it's too hard.

Also, from an earlier email to @mmcky

Would you mind to add this abstract to the networks text homepage?

This textbook is an introduction to economic networks, intended for
students and researchers in the fields of economics and applied
mathematics. The textbook emphasizes quantitative modeling, with the
main underlying tools being graph theory, linear algebra, fixed point
theory and programming. The text is suitable for a one-semester
course, taught either to advanced undergraduate students who are
comfortable with linear algebra or to beginning graduate students.

Perhaps it could go after authors.

Many thanks.

1. I think it would be nice to label the plots in more detail. i.e. Figure 1.1 on page 3, to have 'exporters' and 'consumers', Figure 1.2 to mention that node size = export value in a caption
2. On page 46, it might be nice to have code that sums the rows and columns for the in/out-degree measures (given that the less efficient version was given above)
3. Page 49, space between 'where c' in the Theorem equation
4. Page 57, space between 'For example, Figure 1.24'

Hi, love the textbook.

There might be a slight error in the discussion of weakly chained sub-stochastic matrices.

Consider [[0.5 0.5],[0 0]] as a 2x2 matrix. This seems to meet the definition of sub-stochastic on p.100, but I don't think it meets the definition of weakly chained sub-stochastic matrices despite having a spectral radius of 0.5.

As for m=2, there does not exist an i st m->i on the induced weighted digraph.

Apologies if this is my confusion.

Best wishes,
Dan
