$$S^1$$-Invariant Laplacian Flow

نویسندگان

چکیده

The Laplacian flow is a geometric introduced by Bryant as way for finding torsion free $$G_2$$ -structures starting from closed one. If the invariant under $$S^1$$ action then it descends to of SU(3)-structures on 6-manifold. In this article we derive expressions these evolution equations. our search examples discover first inhomogeneous shrinking solitons, which are also gradient. We show that any compact non-torsion soliton admits no infinitesimal symmetry.

A note on the bounds of Laplacian-energy-like-invariant

The Laplacian-energy-like of a simple connected graph G is defined as LEL:=LEL(G)=∑_(i=1)^n√(μ_i ), Where μ_1 (G)≥μ_2 (G)≥⋯≥μ_n (G)=0 are the Laplacian eigenvalues of the graph G. Some upper and lower bounds for LEL are presented in this note. Moreover, throughout this work, some results related to lower bound of spectral radius of graph are obtained using the term of ΔG as the num...

On the Invariant Spectrum of S1−invariant Metrics on S

A theorem of J. Hersch (1970) states that for any smooth metric on S, with total area equal to 4π, the first nonzero eigenvalue of the Laplace operator acting on functions is less than or equal to 2 (this being the value for the standard round metric). For metrics invariant under the standard S-action on S, one can restrict the Laplace operator to the subspace of S-invariant functions and consi...

Scale Invariant Optical Flow

Scale variation commonly arises in images/videos, which cannot be naturally dealt with by optical flow. Invariant feature matching, on the contrary, provides sparse matching and could fail for regions without conspicuous structures. We aim to establish dense correspondence between frames containing objects in different scales and contribute a new framework taking pixel-wise scales into consider...
