ФОРСЕЙТ ЭНДРЮ РАССЕЛ
(Форсайт, Andrew Russel Forsyth) — английский математик. Род. в 1858. В 1882 г. проф. математики в университетском колледже в Ливерпуле. С 1884 г. — в Кембридже, как в Trinity College, так и в университете. Учено-литературная деятельность Ф. началась с 1880 г. статьями "Vortex-motion in viscous fluids" ("The Messenger of Mathematics", IX) и 
("The Quarterly Journal of pure and applied Mathematics", XVII). Из последующих его работ, весьма многочисленных, назовем следующие "Symm. function of the roots of an equation" ("Messenger of Math.", X, 1881); "Porism of the in- and circumscribed polygon" (там же). "A series for 1/π" (там же, XII, 1883); "On a theorem of Jacobi's" ("Quart. Journal of Math.", 1882); "Approx. formula for x when x is large" ("Reports of the British Association for the advancement of science", 1884); "In- and circumscribed polyedra" ("Proceedings of the London Mathematical Society", XIV, 1883); "Mem. on the theta-functions, patric those of 2 variables" ("Philosophical Transactions of the Royal Society of London", CLXXIII, 1883); "Abel's theorem and Abelian functions" ("Proceedings of the Royal Society of London", XXXIV,). Из отдельно изданных сочинений Ф. назовем "Treatise on differential Equations" (Л., 1885; нем. перев. Мазера с дополнением, Брауншвейг, 1889); "А Treatise on the theory of functions of a complex variable" (Кембридж, 1893); "A treatise on the theory of differential equations, part. 1. Exact equations and Pfaff's problem" (Эдинбург, 1890; нем. перевод Мазера, часть I, Лпц., 1893); "Systems of Ternariants that are Algebraically complete" (1889); "Systems of Quaternariants that are algebraically complete" (1889); "A class, of functional invariants" (1889); "Invariants, convariants and quotient derivates associated with linear differential equations" (1888).
