Local Structure of Convex Surfaces near Regular and Conical Points
Axioms, 2022 Consider a point on a convex surface in Rd, d≥2 and a plane of support Π to the surface at this point. Draw a plane parallel with Π cutting a part of the surface.

Algebraic Tangent Cones of Reflexive Sheaves [PDF]
International Mathematics Research Notices, 2018 Abstract We study the notion of algebraic tangent cones at singularities of reflexive sheaves. These correspond to extensions of reflexive sheaves across a negative divisor. We show the existence of optimal extensions in a constructive manner, and we prove the uniqueness in a suitable sense.

A case in which irreducibility of an analytic germ implies irreducibility of the tangent cone [PDF]
, 1973 There are simple examples in which a variety is irreducible at a point but has a reducible tangent cone. The following theorem is proved. If X p {X_p} is an irreducible analytic germ and if the ...

The asymmetry on singularities of tangent surfaces in contact-cone Legendre-null duality [PDF]
, 2011 We give the generic classification on singularities of tangent surfaces to Lengendre curves and to null curves by using the contact-cone duality between the contact 3-sphere and the Lagrange-Grassmannian with cone structure of a symplectic 4-space.

Spacelike developable surfaces through a common line of curvature in Minkowski 3-space
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 This paper studies the problem to construct a spacelike developable surface possessing a given non-null parametric curve as the line of curvature in Minkowski 3-space.

Sequential Bouligand Tangent Cone and Clarke Tangent Cone in a Real Normed Space [PDF]
, 2014 In this paper, we discuss several basic properties of cone, convex, tangent cone, and bring to a focus on the sequential Bouligand tangent cone which is also called the contingent cone.
