This short note originated from a short talk of basic category theory in 2022. Category theory was first introduced by Samuel Eilenberg and Saunders Mac Lane in the 20th century. It rapidly became a strong tool in almost all domains of mathematics. Category theory studies the abstract structures of different mathematical objects, and it also has applications on computer science, including AI.1. CategoriesIn this section, we will first lay out the general definition of categories, then we give so ...
When your views.py is too large, it becomes much more difficult to manage your code. So you might want to split views.py into several subviews, each of which contains a single sort of views.To split views.py, you could follow the following steps. Your original views.py might look like this:import ... def view1(request): pass def view2(request): passNow, create a new folder subviews aside with views.py , i.e. /Django/mysite/MyAPI/subviews. Next, create __init__.py, viewsa.py, and viewsb. ...

In Vue.js, we can define an anchor by RouterLink or HTML tag <a> , while in Nuxt.js, we can additionally use NuxtLink which is similar to RouterLink .<a href="#content">My Link</a> <RouterLink to="#content">My Link</RouterLink> <NuxtLink to="#content">My Link</NuxtLink>However, on loading a page, the above ways would change the url which makes it slow to go to #content . To speed up anchor link and not change the url, there are two ways.The first way is ...
It is known that the homomorphisms between group preserve products. However, the anti-homomorphisms between groups invert products in contrast to the homomorphisms. In this article, we briefly introduce the notion of anti-homomorphisms of groups, and we will study anti-homomorphisms of rings in the next article.1. Anti-homomorphisms of groups.In this section, all groups are not necessarily abelian. For simplicity, we will simply call anti-homomorphism instead of anti-homomorphism of groups.Defin ...
