Regularizing a Singular Special Lagrangian Variety
Suppose M1 and M2 are two special Lagrangian submanifolds with boundary of R , n ≥ 3, that intersect transversally at one point p. The set M1 ∪M2 is a singular special Lagrangian variety with an isolated singularity at the point of intersection. Suppose further that the tangent planes at the intersection satisfy an angle criterion (which always holds in dimension n = 3). Then, M1 ∪ M2 is regula...

Suppose M1 and M2 are two special Lagrangian submanifolds of R 2n with boundary that intersect transversally at one point p. The set M1 ∪M2 is a singular special Lagrangian variety with an isolated singularity at the point of intersection. Suppose further that the tangent planes at the intersection satisfy an angle condition (which always holds in dimension n = 3). Then, M1 ∪ M2 is regularisabl...
متن کاملSingular Behaviour of the Potts Model in the Thermodynamic Limit
The self–duality transformation is applied to the Fisher zeroes near the critical point in the thermodynamic limit in the q > 4 state Potts model in two dimensions. A requirement that the locus of the duals of the zeroes be identical to the dual of the locus of zeroes (i) recovers the ratio of specific heat to internal energy discontinuity at criticality and the relationships between the discon...
متن کاملSingular Behaviour of Finite Approximations to the Addition Model
Instantaneous gelation in the addition model with superlinear rate coe cients is investigated. The conjectured post-gelation solution is shown to arise naturally as the limit of solutions to some nite approximations as the number of equations grows to in nity. Non-existence of continuous solutions to the addition model is also established in that case.
متن کاملSpectral behaviour of GMRES applied to singular systems
The purpose of this paper is to develop a spectral analysis of the Hessenberg matrix obtained by the GMRES algorithm used for solving a linear system with a singular matrix. We prove that the singularity of the Hessenberg matrix depends on the nature of A and some others criteria like the zero eigenvalue multiplicity and the projection of the initial residual on particular subspaces. We also in...
