Web[From the foreword by B. Teissier] The main ideas of the proof of resolution of singularities of complex-analytic spaces presented here were developed by Heisuke Hironaka in the … WebAdditional references for resolution of singularities include Cutkowsky [29], Faber and Hauser [33], Hauser [59], Hironaka [60], Koll´ar [73], Villamayor [120, 121, 32], and Włodarczyk [122, 123]. Proofs of special cases of resolution of singularities for real and complex analytic varieties were previously provided by Bierstone and Milman [9 ...
WebIdealistic Filtration Program (IFP) is an approach to the resolution of singularities of algebraic varieties. The object of IFP is idealistic filtraion, which is a kind of algebraic reformulation of Hironaka's idealistic exponent (or Villamayor's basic object, Bierstone-Milman's presentation, and so on). Its saturations, namely differential ... In algebraic geometry, the problem of resolution of singularities asks whether every algebraic variety V has a resolution, a non-singular variety W with a proper birational map W→V. For varieties over fields of characteristic 0 this was proved in Hironaka (1964), while for varieties over fields of characteristic p it is an … See more Originally the problem of resolution of singularities was to find a nonsingular model for the function field of a variety X, in other words a complete non-singular variety X′ with the same function field. In practice it is more … See more The problem of resolution of singularities in higher dimensions is notorious for many incorrect published proofs and announcements of proofs that never appeared. Zariski's method For 3-folds the … See more There are many constructions of strong desingularization but all of them give essentially the same result. In every case the global object … See more Every algebraic curve has a unique nonsingular projective model, which means that all resolution methods are essentially the same … See more Surfaces have many different nonsingular projective models (unlike the case of curves where the nonsingular projective model is unique). … See more It is easy to extend the definition of resolution to all schemes. Not all schemes have resolutions of their singularities: Grothendieck (1965, section 7.9) harvtxt error: no target: … See more Multiplicity need not decrease under blowup The most obvious invariant of a singularity is its multiplicity. However this need not decrease under … See more

Not necessarily, I don't think. There are surface singularities (though I can't recall an example easily, but one whose resolution has exceptional divisor an elliptic curve) for which if you blow up at a point you get a singular curve.
