TERMS OF USE
Terms updated on september 11, 2026
Preamble
The official language of this internet presence is French. Any potential disputes concerning it will therefore be settled in this language. In case of doubt in the interpretation of these legal notices, the French version serves as the basis for resolving misunderstandings. It is desired that these be resolved amicably first.
As a courtesy to foreign visitors, I offer a partial English and German version of my work.
The domains hades-home.fr and tla-periat.fr are linked and constitute a private internet presence. It is not a commercial showcase since I offer my work there for free. Paid works of which I am the author can only be ordered from the publishing house BoD-France (and provided that the HTML widget is activated).
Cookie management
General
There are several types of cookies.
1) Cookies that are strictly necessary for the operation of the sites used by the host (here www.sitew.com) to allow access to the hosted site, in this case: hades-home.fr and tla-periat.fr.
They cannot be refused.
2) Third-party cookies linked to the use of optional features offered by the hosted site.
They can be refused.
Refusing certain optional cookies may result in the inability to view certain parts of the site; notably: some mathematical demonstrations.
Optional cookies: description and management
1) Application Programming Interface:
The domains "hades-home.fr" and "tla-periat.fr" offer scientific content. They sometimes make use of mathematical formulas. The simplest ones can be read without the use of a specialized program.
On the other hand, on certain pages featuring more sophisticated formulations, equations can be viewed thanks to the use of the MathJax program.
For your information:
a) To view these parts, which is entirely your choice, you must accept, meaning authorize the use of this application.
b) Your acceptance in principle causes no profiling and no deposition of advertising cookies.
c) However, when you access a page containing equations viewable thanks to the MathJax application, it may be that:
(i) the content delivery network (CDN) delivering information from the site host's servers loads technical cookies for security reasons or delivery performance.
Refusing these cookies may result in an unability to read the equations.
(ii) the MathJax program may eventually place a cookie on your computer to save the configuration chosen by you (potential zoom size, rendering type, etc.).
2) Audience measurement
The site uses the fully anonymized features of the "Google Search Console". However:
You can refuse these measurements.
3) Additional information regarding the storage of cookies on your device
Generally speaking, direct management of cookies stored on your computer equipment remains possible at all times, independently of the settings explained previously, by using the settings of your internet interface (browser), for example: Google, Google Chrome, Edge, Mozilla, Opera, etc.
It is often enough to click on the symbol located in front of the internet address you are visiting.
A context menu opens and it becomes possible to click on a line labeled as follows (or equivalent in meaning): "cookies and website data". It offers more or moins rapid access to information and options allowing you whether or not to eliminate the cookies stored on your device.
Intellectual Property
The author and writer of the content presented on this site is Thierry PERIAT: contact@tla-periat.fr
Article L122-4 of the French Intellectual Property Code states that "any full or partial representation or reproduction made without the consent of the author or his successors in title or assigns is unlawful. The same applies to translation, adaptation or transformation, arrangement or reproduction by any art or process whatsoever".
The reproduction, representation or distribution, by any means whatsoever, of a work of the mind in violation of the author's rights as defined and regulated by law constitutes the offense of copyright infringement (Article L.335-3 of the French Intellectual Property Code).
Article L122-5 of the Intellectual and Artistic French Property Code defines the uses that may be made of a work. For example, under paragraphs 1° and 2°, "copies or reproductions strictly reserved for the private use of the copier and not intended for collective use are authorized".
Costs associated with your visits
Access to the hades-home.fr and tla-periat.fr domains is of course only possible if you have an internet subscription. The costs related to this subscription are entirely your responsibility.
The same applies to any costs (if any) that might be incurred by your use of the MathJax application necessary to view certain portions of these domains.
External links to other domains and websites
Hyperlinks are made available on certain pages. They provide access to various external domains and websites. They are offered after being checked and when this procedure is authorized (with or without prior request for authorization). However, I have no influence over these domains and their content. This is the reason why I cannot assume any responsibility for their content. This remains exclusively the responsibility of their respective owners and operators. Continuous monitoring of these hyperlinks is not humanly feasible.
In the event that you notice the existence of inappropriate content, I would be grateful if you could report it to me; I will then take the necessary action to deactivate it.
