Robust Time-Difference-of-Arrival (TDOA) Localization Using Weighted Least Squares with Cone Tangent Plane Constraint [PDF]
Sensors, 2018 Finding the position of a radiative source based on time-difference-of-arrival (TDOA) measurements from spatially separated receivers has been widely applied in sonar, radar, mobile communications and sensor networks.

Tangent Cones and Quasi-Interiorly Tangent Cones to Multifunctions [PDF]
Transactions of the American Mathematical Society, 1983 R. T. Rockafellar has proved a number of rules of subdifferential calculus for nonlocally lipschitzian real-valued functions by investigating the Clarke tangent cones to the epigraphs of such functions. Following these lines we study in this paper the tangent cones to the sum and the composition of two multifunctions.

Cohen-Macaulayness of tangent cones [PDF]
Proceedings of the American Mathematical Society, 1999 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.

Idealistic exponents: Tangent cone, ridge, characteristic polyhedra [PDF]
, 2021 We study Hironaka's idealistic exponents over Spec (Z). We give an idealistic interpretation of the tangent cone, the directrix, and the ridge. The main purpose is to introduce the notion of characteristic polyhedra of idealistic exponents and deduce ...

On inner calmness*, generalized calculus, and derivatives of the normal cone mapping [PDF]
Journal of Nonsmooth Analysis and Optimization, 2021 In this paper, we study continuity and Lipschitzian properties of set-valued mappings, focusing on inner-type conditions. We introduce new notions of inner calmness* and, its relaxation, fuzzy inner calmness*.

On Tangent Cones of Schubert Varieties [PDF]
Arnold Mathematical Journal, 2017 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.
