Berhanu, Shiferaw (ed.) et al., Recent progress on some problems in several complex variables and partial differential equations. Papers presented at the international conferences on partial differential equations and several complex variables, Wuhan, China, June 9–13, 2004 and on complex geometry and related fields, Shanghai, China, June 21–24, 2004. Providence, RI: American Mathematical Society (AMS) (ISBN 0-8218-3921-7/pbk). Contemporary Mathematics 400, 53-64 (2006).
The authors consider summability problems for singular PDE in which the formal solutions are convergent for small \(t\) but divergent for small \(x\). The \(k\)-summability of these series has been proved.
