Dominant topologies in Euclidean quantum gravity
The dominant topologies in the Euclidean path integral for quantum gravity differ sharply according to the sign of the cosmological constant. For 3 > 0, saddle points can occur only for topologies with vanishing first Betti number and finite fundamental group. For 3 < 0, on the other hand, the path integral is dominated by topologies with extremely complicated fundamental groups; while the cont...
متن کاملThe Sum over Topologies in Three-Dimensional Euclidean Quantum Gravity
In Hawking’s Euclidean path integral approach to quantum gravity, the partition function is computed by summing contributions from all possible topologies. The behavior such a sum can be estimated in three spacetime dimensions in the limit of small cosmological constant. The sum over topologies diverges for either sign of Λ, but for dramatically different reasons: for Λ > 0, the divergent behav...
متن کاملQuasi-Euclidean Recovery from Unknown but Complete Orbital Motion
In this technical report, we address the problem of quasi-Euclidean reconstruction (i.e., close to scaled Euclidean but not necessarily exact) using an uncalibrated camera with a specific known type of motion, namely unknown but complete orbital motion. By orbital motion, we mean pure rotation about a fixed arbitrary axis. Exact scaled Euclidean reconstruction for orbital motion is not possible...
متن کاملFaster Joins , Self - Joins and
We propose a new algorithm, called Stripe-join, for performing a join given a join index. Stripe-join is inspired by an algorithm called \Jive-join" developed by Li and Ross. Stripe-join makes a single sequential pass through each input relation, in addition to one pass through the join index and two passes through a set of temporary les that contain tuple identiiers but no input tuples. Stripe...
متن کاملTameness of pseudovariety joins
The concept of tameness of a pseudovariety was introduced by Almeida and Steinberg [1] as a tool for proving decidability of the membership problem for semidirect products of pseudovarieties. Recall that the join V ∨ W of two pseudovarieties V and W is the least pseudovariety containing both V and W. This talk is concerned with the problem of proving tameness of joins. This problem was consider...
