Three point covers with bad reduction
We study Galois covers of the projective line branched at three points with bad reduction to characteristic p, under the condition that p strictly divides the order of the Galois group. As an application of our results, we prove that the field of moduli of such a cover is at most tamely ramified at p.
متن کاملAn MDCT domain three-point interpolation-based low-complexity frequency estimator
Signal frequency estimation is a problem of significance in many applications including audio signal processing. Compressed domain audio frequency estimators that directly use the modified discrete cosine transform (MDCT) coefficients are suitable for low-complexity audio applications. A new frequency estimation approach, which can obtain the estimated value from a simple combination of three M...
متن کاملBias Reduction for Direct Frequency Estimator of Complex Sinusoid
Frequency estimation of single-tone complex sinusoid is a fundamental problem in signal processing. An efficient way to estimate the frequency is to directly calculate the frequency from three discrete Fourier transform coefficients in the neighborhood of peak magnitude spectrum. Because of the approximation used in the calculation, these direct estimators exhibit non-uniform biases. In this pa...
متن کاملStable reduction of three point covers
1.1 Ramification in the field of moduli Let X be a smooth projective curve over C. A celebrated theorem of Belyi states that X can be defined over a number field K if and only if there exists a rational function f on X with exactly three critical values, see [2], [11]. If such a function f exists, we can normalize it in such a way that the critical values are 0, 1 and ∞. After this normalizatio...
متن کاملA Convergent Frequency Estimator
Online identification of sinusoidal components is an important problem that occurs in active noise control, vibration suppression, on line health monitoring, and radar, sonar, and seismic applications. We adopt a new approach to this identification problem which consists of the utilization of the underlying nonlinearlity and an algorithm that is based on the nonlinear parameterization. The algo...
