Milnor Number Equals Tjurina Number for Functions on Space Curves [PDF]

open access: yesJournal of the London Mathematical Society, 2001
In many situations in complex geometry one can define a Milnor number, \(\mu\), that describes the rank of some vanishing homology, and a Tjurina number, \(\tau\), the dimension of the base of a semi-universal deformation. For example, for a hypersurface singularity \(X=V(f)\), one has \[ \mu=\dim {\mathcal O}/J_f,\quad \tau=\dim {\mathcal O}/(f,J_f), \

On Sextic Curves with Big Milnor Number [PDF]

open access: yes, 2002
In this work we present an exhaustive description, up to projective isomorphism, of all irreducible sextic curves in ℙ2 having a singular point of type , A n ,n⩾15 n ≥ 15, only rational singularities and global Milnor number at least 18. Moreover, we develop a method for an explicit construction of sextic curves with at least eight — possibly ...

A formula for the Milnor Number

open access: yes, 1995
We give a formula for the Milnor number of a germ (X,0) subset of (C-n+1,0) defined by f=0, f=f(d)+f(d+k)+...epsilon C {x(0),...,x(n)}, and such that Sing(D) boolean AND Z (f(d+k)) = circle divide, where D=Z (f(d)) subset of P-C(n). We prove that the topological type of (X,0) is determined by the d+k-jet of f.

Milnor number of pairs and pencils of plane holomorphic germs

open access: yesBulletin de la Société mathématique de France, 2015
Summary: We introduce a Milnor number of pairs of plane holomorphic germs and investigate the relation between the Milnor numbers in a pencil of such functions.

Presentation of preload and afterload to isolated heart preparations. [PDF]

open access: yesJ Physiol
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

Proximal Pulmonary Artery Stiffening as a Biomarker of Cardiopulmonary Aging. [PDF]

open access: yesAging Cell
Mouse models revealed age‐associated increased circumferential stiffness of the proximal pulmonary artery that was associated with reorientation of collagen and decreased function of the lung and right ventricle. Age‐related transcriptional changes were indicative of senescence, ECM turnover, TGFβ signaling, and altered intercellular signaling among ...

On the Milnor number of non-isolated singularities of holomorphic foliations and its topological invariance [PDF]

open access: yes, 2021
We define the Milnor number -- as the intersection number of two holomorphic sections -- of a one-dimensional holomorphic foliation $\mathscr{F}$ with respect to a compact connected component $C$ of its singular set.

Deformations of functions and F-manifolds [PDF]

open access: yes, 2004
We study deformations of functions on isolated singularities. A unified proof of the equality of Milnor and Tjurina numbers for functions on isolated complete intersections singularities and space curves is given.
