Low-rank tensor approximation for Chebyshev interpolation in parametric option pricing
Treating high dimensionality is one of the main challenges in the development of computational methods for solving problems arising in finance, where tasks such as pricing, calibration, and risk assessment need to be ... -
Lowest weight modules of Sp_4(R) and nearly holomorphic Siegel modular forms
We undertake a detailed study of the lowest weight modules for the Hermitian symmetric pair (G,K), where G=Sp_4(R) and K is its maximal compact subgroup. In particular, we determine K-types and composition series, and write ... -
Lp-Lq multipliers on locally compact groups
(Elsevier, 2019-09-25)In this paper we discuss the Lp-Lq boundedness of both spectral and Fourier multipliers on general locally compact separable unimodular groups G for the range 1<p≤2≤q<∞. As a consequence of the established Fourier multiplier ... -
LSTM-CNN: An efficient diagnostic network for Parkinson's disease utilizing dynamic handwriting analysis.
(2024-04)BACKGROUND AND OBJECTIVES: Dynamic handwriting analysis, due to its noninvasive and readily accessible nature, has emerged as a vital adjunctive method for the early diagnosis of Parkinson's disease (PD). An essential step ... -
Macroscopic properties of buyer-seller networks in online marketplaces.
(2022-09)Online marketplaces are the main engines of legal and illegal e-commerce, yet their empirical properties are poorly understood due to the absence of large-scale data. We analyze two comprehensive datasets containing 245M ... -
Magnitude meets persistence. Homology theories for filtered simplicial sets
(International Press, 2022-08-24)The Euler characteristic is an invariant of a topological space that in a precise sense captures its canonical notion of size, akin to the cardinality of a set. The Euler characteristic is closely related to the homology ... -
The Manin constant and the modular degree
The Manin constant $c$ of an elliptic curve $E$ over $\mathbb{Q}$ is the nonzero integer that scales the pullback of a N\'{e}ron differential under a minimal parametrization $\phi\colon X_0(N)_{\mathbb{Q}} \twoheadrightarrow ...
