Optimal Multi-frame Correspondence with Assignment Tensors
Establishing correspondence between features of a set of images has been a long-standing issue amongst the computer vision community. We propose a method that solves the multi-frame correspondence problem by imposing a rank constraint on the observed scene, i.e. rigidity is assumed. Since our algorithm is based solely on a geometrical (global) criterion, it does not suffer from issues usually a...
متن کاملNambu tensors and commuting vector fields
Takhtajan has recently studied the consistency conditions for Nambu brackets, and suggested that they have to be skew-symmetric, and satisfy Leibnitz rule and the Fundamental Identity (FI, it is a generalization of the Jacobi identity). If the n-th order Nambu brackets in dimension N is written as {f1, . . . , fn} = ηi1...in∂i1f1 · · · ∂infn (where the iα summations range over 1 . . . N), the F...
متن کاملQuantum Mechanics of Yano tensors: Dirac equation in curved spacetime
In spacetimes admitting Yano tensors the classical theory of the spinning particle possesses enhanced worldline supersymmetry. Quantum mechanically generators of extra supersymmetries correspond to operators that in the classical limit commute with the Dirac operator and generate conserved quantities. We show that the result is preserved in the full quantum theory, that is, Yano symmetries are ...
متن کاملG2 and some exceptional Witt vector identities
We find some new one-parameter families of exponential sums in every odd characteristic whose geometric and arithmetic monodromy groups are G2. 1. The exceptional identities Fix a prime p, and consider the p-Witt vectors of length 2 as a ring scheme over Z. The addtion law is given by (x, a) + (y, b) := (x+ y, a+ b+ (x + y − (x+ y))/p). The multiplication law is given by (x, a)(y, b) := (xy, xb...
متن کاملThe Cosmological Constant Problem and Quantum Spacetime Reference Frame
We generalize the idea of quantum clock time to quantum spacetime reference frame via physical realization of a reference system by quantum rulers and clocks. Omitting the internal degrees of freedom (such as spins) of the physical rulers and clocks, only considering their metric properties, the spacetime reference frame is described by a bosonic non-linear sigma model. We study the quantum beh...
