Miwa, Tetsuji (ed.) et al., Algebraic analysis and around in honor of Professor Masaki Kashiwara’s 60th birthday. Tokyo: Mathematical Society of Japan (ISBN 978-4-931469-51-8/hbk). Advanced Studies in Pure Mathematics 54, 293-353 (2009).
Summary: We propose a definition of (polarized) wild twistor \(\mathcal D\)-modules, generalizing to objects with irregular singularities that of (polarized) regular twistor \(\mathcal D\)-modules. We give a precise analysis in dimension one.
