A Convergent Fourier Spectral Galerkin Method for the Fractional Camassa–Holm Equation
ABSTRACT We analyze a Fourier spectral Galerkin method for the fractional Camassa–Holm (fCH) equation involving a fractional Laplacian of exponent α∈[1,2]$$ \alpha \in \left[1,2\right] $$ with periodic boundary conditions. The semi‐discrete scheme preserves both mass and energy invariants of the fCH equation.

Equioscillatory property of the Laguerre polynomials
\(L^{(\alpha)}_k\) is the orthonormal Laguerre polynomial of degree \(k\) and \(d_m\), \(d_M\) are some approximations for the extreme zeros. The authors show that the function \[ ((x- d_m)(x- d_M))^{1/4} x^{\alpha/2} e^{-{x\over 2}}L^{(\alpha)}_k(x) \] is almost equi-oscilating with the amplitude \(\sqrt{{2\over\pi}}\) provided \(k\) and \(\alpha ...

Treeline Provides a Unified Strategy for Optimising Phylogenetic Trees Under Alternative Criteria
ABSTRACT The choice of optimality criterion is a key consideration in phylogenetic studies. Recent work challenges the notion that more computationally demanding optimisation objectives result in better phylogenetic trees. This finding underscores the importance of comparing trees across optimisation objectives in addition to different models of ...

Extended Laguerre Polynomials Associated with Hermite, Bernoulli, and Euler Numbers and Polynomials
Let Pn={p(x)∈ℝ[x]∣deg p(x)≤n} be an inner product space with the inner product 〈p(x),q(x)〉=∫0∞xαe-xp(x)q(x)dx, where p(x),q(x)∈Pn and α∈ℝ with α>-1. In this paper we study the properties of the extended Laguerre polynomials which are an orthogonal basis

Financial Statement Information and Equity Value: The Role of Real Options Characteristics
ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...
