On a Riemann surface the Poincaré lemma states that every closed 1-form or 2-form is locally exact. [2] Thus if ω is a smooth 1-form with dω = 0 then in some open neighbourhood of a given point there is a smooth function f such that ω = df in that neighbourhood; and for any smooth 2-form Ω there is a smooth 1-form ω defined in some open neighbourhood of a given point such that Ω = dω ...
He established and developed the theory of complex-analytic spaces in joint work with Hans Grauert. Until his retirement in 1995, he was a professor for complex analysis in Münster . Remmert wrote two books on number theory and complex analysis , which contain a huge amount of historical information together with references on important papers ...
Initially, Kreider continued research and writing in recursive function theory, working with Robert W. Ritchie. But he increasingly turned his attention to mathematical pedagogy, [ 7 ] writing textbooks in recursive function theory, [ 8 ] differential equations , and linear analysis with colleagues in the Department of Mathematics.
The complex-valued function () = (,) + (,) is pseudoanalytic with respect to an admissible at the point if all partial derivatives of and exist and satisfy the following conditions: u x = σ ( x , y ) v y , u y = − σ ( x , y ) v x {\displaystyle u_{x}=\sigma (x,y)v_{y},\quad u_{y}=-\sigma (x,y)v_{x}}
The term resurgent function (from Latin: resurgere, to get up again) comes from French mathematician Jean Écalle's theory of resurgent functions and alien calculus. The theory evolved from the summability of divergent series (see Borel summation) and treats analytic functions with isolated singularities. He introduced the term in the late ...
From we can build more terms, such as which is the kind of unary type-level operators (e.g.: is read as “ List is a function from types to types”, that is, a polymorphic type). The rules restrict how we can form new kinds.
