Homological algebra quiz: 3 questions
Three questions on the Homological algebra card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
A central concept is that of chain complexes, which can be studied through their ______ and cohomology.
Answer
homology. A central concept is that of chain complexes, which can be studied through their homology and cohomology. From the Homological algebra article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Memory card. Memory card 40,000 · Homological algebra 32,000 · Agricultural engineering 24,000 · Felix Adler 18,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is a relatively young discipline, whose origins can be traced to investigations in combinatorial topology and abstract algebra at the end of the 19th century, chiefly by Henri Poincaré and David Hilbert.
- Homological algebra is the study of homological functors and the intricate algebraic structures that they entail, its development was closely intertwined with the emergence of category theory.
- A central concept is that of chain complexes, which can be studied through their homology and cohomology.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Homological algebra article was read about 32,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 43: each hit it takes is cut by 17 %.
How to get Homological algebra
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
