        Theory of infinitely near singular points

        Heisuke Hironaka 대한수학회 2003 대한수학회지 Vol.40 No.5

        The notion of infinitely near singular points, classical in the case of plane curves, has been generalized to higher dimensions in my earlier articles (\cite{hiro:garden}, \cite{hiro:intromadrid}, \cite{hiro:idealexpo}). There, some basic techniques were developed, notably the three technical theorems which were \emph{ Differentiation Theorem}, \emph{Numerical Exponent Theorem} and \emph{Ambient Reduction Theorem} \cite{hiro:idealexpo}. In this paper, using those results, we will prove the \emph{Finite Presentation Theorem}, which the auther believes is the first of the most important milestones in the general theory of infinitely near singular points. The presentation is in terms of a \emph{finitely generated} graded algebra which describes the total aggregate of the trees of infinitely near singular points. The totality is a priori very complex and intricate, including all possible successions of permissible blowing-ups toward the reduction of singularities. The theorem will be proven for singular data on an ambient algebraic shceme, regular and of finite type over any perfect field of any characteristics. Very interesting but not yet apparent connections are expected with many such works as (\cite{abhy:planecurve}, \cite{yous:newtonpoly}).

        THEORY OF INFINITELY NEAR SINGULAR POINTS

        Hironaka, Heisuke Korean Mathematical Society 2003 대한수학회지 Vol.40 No.5

        The notion of infinitely near singular points, classical in the case of plane curves, has been generalized to higher dimensions in my earlier articles ([5], [6], [7]). There, some basic techniques were developed, notably the three technical theorems which were Differentiation Theorem, Numerical Exponent Theorem and Ambient Reduction Theorem [7]. In this paper, using those results, we will prove the Finite Presentation Theorem, which the auther believes is the first of the most important milestones in the general theory of infinitely near singular points. The presentation is in terms of a finitely generated graded algebra which describes the total aggregate of the trees of infinitely near singular points. The totality is a priori very complex and intricate, including all possible successions of permissible blowing-ups toward the reduction of singularities. The theorem will be proven for singular data on an ambient algebraic shceme, regular and of finite type over any perfect field of any characteristics. Very interesting but not yet apparent connections are expected with many such works as ([1], [8]).
