In order to meet these industrial expectations, applied mathematicians are facing a formidable challenge summarized by these words - nonlinearity and coupling. This book is unique as it proposes truly original solutions: (1) Using hypercomputation in quadratic algebras, as opposed to the traditional use of linear vector spaces in the 20th century; (2) complementing the classical linear logic by the complex logic whichSocial sciencesData processingQualitative researchData processingSocial sciencesData processing.Qualitative researchData processing.511.8Chaitin-Chatelin Françoise54166MiAaPQMiAaPQMiAaPQBOOK9910792082703321Qualitative computing3758384UNINA
