Rules
-
π Be Nice!
- Treat others with respect and dignity. Friendly banter is okay, as long as it is mutual; keyword: friendly.
-
ποΈ Community Standards
- Comics should be a full story, from start to finish, in one post.
- Posts should be safe and enjoyable by the majority of community members, both here on lemmy.world and other instances.
- Any comic that would qualify as raunchy, lewd, or otherwise draw unwanted attention by nosy coworkers, spouses, or family members should be tagged as NSFW.
- Moderators have final say on what and what does not qualify as appropriate. Use common sense, and if need be, err on the side of caution.
-
𧬠Keep it Real
- Comics should be made and posted by real human beans, not by automated means like bots or AI. This is not the community for that sort of thing.
-
π½οΈ Credit Where Credit is Due
- Comics should include the original attribution to the artist(s) involved, and be unmodified. Bonus points if you include a link back to their website. When in doubt, use a reverse image search to try to find the original version. Repeat offenders will have their posts removed, be temporarily banned from posting, or if all else fails, be permanently banned from posting.
- Attributions include, but are not limited to, watermarks, links, or other text or imagery that artists add to their comics to use for identification purposes. If you find a comic without any such markings, it would be a good idea to see if you can find an original version. If one cannot be found, say so and ask the community for help!
-
π Post Formatting
- Post an image, gallery, or link to a specific comic hosted on another site; e.g., the author's website.
- Meta posts about the community should be tagged with [Meta] either at the beginning or the end of the post title.
- When linking to a comic hosted on another site, ensure the link is to the comic itself and not just to the website; e.g.,
β Correct: https://xkcd.com/386/
β Incorrect: https://xkcd.com/
-
π¬ Post Frequency/SPAM
- Each user (regardless of instance) may post up to five (5 π) comics a day. This can be any combination of personal comics you have written yourself, or other author's comics. Any comics exceeding five (5 π) will be removed.
-
π΄ββ οΈ Internationalization (i18n)
- Non-English posts are welcome. Please tag the post title with the original language, and include an English translation in the body of the post; e.g.,
SΓ, por favor [Spanish/EspaΓ±ol]
- Non-English posts are welcome. Please tag the post title with the original language, and include an English translation in the body of the post; e.g.,

πΏ Moderation
- We are human, just like most everybody else on Lemmy. If you feel a moderation decision was made in error, you are welcome to reach out to anybody on the moderation team for clarification. Keep in mind that moderation decisions may be final.
- When reporting posts and/or comments, quote which rule is being broken, and why you feel it broke the rules.

Distributivity is a requirement for non associative algebras. So whatever structure is left is not one of those
What the fuck are you talking about? That's incorrect as a matter of simple fact.
Associativity is a property possessed by a single operation, whereas distribution is a property possessed by pairs of operations. Non-associative algebras aren't even generally ones that posses multiple operations, so how the hell do you think one implies the other?
Edit: actually, while we're on it, your first comment was nonsense too; you don't know what an identity is and you think that there's no notion of inverses without an identity. While that's generally the case there are exceptions like in Latin Squares, which describe the Cayley Tables of finite algebras for which every element can be operated with some other element to produce any one target element. In this way we can formulate a notion of "division" without using an identity.
Algebras have two operations by definition and the one thing they have in common is that the multiplication distributes over addition.
Yes, there is no notion of inverses without an identity, the definition of an inverse is in terms of an identity.
Stop posting.
Do you think a group isn't an algebra? What, by your definitions make an "Algebra" different from a "Ring"?
A group is not an algebra. A group consists of a single associative binary operation with an identity element and inverses for each element.
A ring is an abelian (commutative) group under addition, along with an additional associative binary operation (multiplication) that distributes over addition. The additive identity is called zero.
A field is a ring in which every nonzero element has a multiplicative inverse.
A vector space over a field consists of an abelian group (the vectors) together with scalar multiplication by elements of the field, satisfying distributivity and compatibility conditions.
A non-associative algebra is a vector space equipped with a bilinear multiplication operation that distributes over vector addition and is compatible with scalar multiplication.
An (associative) algebra is a non-associative algebra whose multiplication operation is associative.
You can read more about these definitions online and in textbooks - these are standard definitions. If you are using different definitions, then it would help your case to provide them so we can better understand your claims.
