The goal of this article is to provide a construction and classification, in the case of two complex dimensions, of the possible tangent cones at points of limit spaces of non-collapsed sequences of Kähler-Einstein metrics with cone singularities.

On Certain Classes of Curve Singularities with Reduced Tangent Cone [PDF]
We study a class of rational curves with an ordinary singular point, which was introduced in [Geramita and Orecchia, Minimally Generating Ideals Defining Certain Tangent Cones, J. of Algebra 78, No. 1 (1982), 36 – 57].

Singularity of Mean Curvature Flow of Lagrangian Submanifolds [PDF]
In this article we study the tangent cones at first time singularity of a Lagrangian mean curvature flow. If the initial compact submanifold is Lagrangian and almost calibrated by Re\Omega in a Calabi-Yau n-fold (M,\Omega), and T>0 is the first blow-up ...

Blending Cylinders and Cones using Canal Surfaces
There is reviewed the construction of a rational blending surface between cylinders and cones in some interlocation cases. This surface is constructed as a patch of rolling ball envelope, i.e.

On Tangent Cones of Schubert Varieties [PDF]
We consider tangent cones of Schubert varieties in the complete flag variety, and investigate the problem when the tangent cones of two different Schubert varieties coincide. We give a sufficient condition for such coincidence, and formulate a conjecture that provides a necessary condition.

A notion of rectifiability modeled on Carnot groups [PDF]
We introduce a notion of rectifiability modeled on Carnot groups. Precisely, we say that a subset E of a Carnot group M and N is a subgroup of M, we say E is N-rectifiable if it is the Lipschitz image of a positive measure subset of N.

Tangent cones to positive-(1,1) De Rham currents [PDF]
We consider positive-(1,1) De Rham currents in arbitrary almost complex manifolds and prove the uniqueness of the tangent cone at any point where the density does not have a jump with respect to all of its values in a neighbourhood.

Cohen-Macaulayness of tangent cones [PDF]
We give a criterion for checking the Cohen-Macaulayness of the tangent cone of a monomial curve by using the Gröbner basis. For a family of monomial curves, we give the full description of the defining ideal of the curve and its tangent cone at the origin.

Algebraic vertices of non-convex polyhedra [PDF]
In this article we define an algebraic vertex of a generalized polyhedron and show that it is the smallest set of points needed to define the polyhedron.

Rigidity of irreducible Hermitian symmetric spaces of the compact type under K"ahler deformation [PDF]
We study deformations of irreducible Hermitian symmetric spaces $S$ of the compact type, known to be locally rigid, as projective-algberaic manifolds and prove that no jump of complex structures can occur.
