Multi Black Holes and Earthquakes on Riemann surfaces with boundaries [PDF]
, 2009 We prove an "Earthquake Theorem" for hyperbolic metrics with geodesic boundary on a compact surfaces $S$ with boundary: given two hyperbolic metrics with geodesic boundary on a surface with $k$ boundary components, there are $2^k$ right earthquakes ...

On series with alternating signs in the Euclidean metric [PDF]
Real Analysis Exchange, 1999 Series of the form \[ \sum_{n=1}^\infty(-1)^{a_n} b_n\tag{1} \] are studied, where \((a_n)_1^\infty\in \{0,1\}^{\mathbb{N}}\), \(b_n\) are elements of a real Hilbert space. Mainly the structure of the sets \(C= \{(a_n)_1^\infty\in \{0,1\}^{\mathbb{N}}\): (1) converges\}, \(B= \{(a_n)_1^\infty\in \{0, 1\}^{\mathbb{N}}\): (1) is bounded\} are ...

Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission
, 2011 The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log$(N)$ barrier where $N$ is the number of subcarriers which has been theoretically ...

Systematic analysis of agreement between metrics and peer review in the UK REF [PDF]
, 2019 When performing a national research assessment, some countries rely on citation metrics whereas others, such as the UK, primarily use peer review. In the influential Metric Tide report, a low agreement between metrics and peer review in the UK Research ...

Bumpy Black Holes in Alternate Theories of Gravity
, 2011 We generalize the bumpy black hole framework to allow for alternative theory deformations. We construct two model-independent parametric deviations from the Kerr metric: one built from a generalization of the quasi-Kerr and bumpy metrics and one built ...

Environmental Research Letters, 2013 Agriculture emits a range of greenhouse gases. Greenhouse gas metrics allow emissions of different gases to be reported in a common unit called CO _2 -equivalent. This enables comparisons of the efficiency of different farms and production systems and of

Time-dependent kinetic energy metrics for Lagrangians of electromagnetic type
, 2011 We extend the results obtained in a previous paper about a class of Lagrangian systems which admit alternative kinetic energy metrics to second-order mechanical systems with explicit time-dependence. The main results are that a time-dependent alternative

Local extremality of the Calabi-Croke sphere for the length of the shortest closed geodesic [PDF]
, 2009 Recently, F. Balacheff proved that the Calabi-Croke sphere made of two flat 1-unit-side equilateral triangles glued along their boundaries is a local extremum for the length of the shortest closed geodesic among the Riemannian spheres with conical ...
