Culture of Asia the form of a novel. Early-Modern Japanese literature (17th–19th centuries) developed comparable innovations such as haiku, a form of Japanese poetry that evolved from the ancient "hokku" (Japanese language: 発句) mode. Haiku consists of three lines: the first and third lines each have five "morae" (the rough phonological equivalent of syllables), while the second has seven. Original haiku masters included such figures as Edo period poet Matsuo Bashō (松尾芭蕉); others influenced by Bashō include Kobayashi Issa and Masaoka Shiki. Korean literature begins in the Three Kingdoms Period, and continues through the Goryeo and Joseon dynasties to the modern day. Examples
Invariant of a binary form for the ring of covariants. showed that the ring of invariants of a degree 8 form is generated by 9 invariants of degrees 2, 3, 4, 5, 6, 7, 8, 9, 10, and the ring of covariants is generated by 69 covariants. August von Gall () and confirmed the generators for the ring of invariants and showed that the ideal of relations between them is generated by elements of degrees 16, 17, 18, 19, 20. showed that the algebra of invariants of a degree 9 form is generated by 92 invariants. Cröni, Hagedorn, and Brouwer computed 476 covariants, and Lercier
