DOI: 10.1007/s10474-019-00934-5
Abstract: In the context of Riesz basis, studies on classical system of exponentials find their origin in the celebrated 1934’s work of Paley and Wiener. The stability question of exponential frames was considered in 1952 by… read more here.

DOI: 10.1088/1475-7516/2018/11/023
Abstract: We study the correspondence between models of a self-interacting canonical complex scalar field and P(X)-theories/shift-symmetric k-essence. Both describe the same background cosmological dynamics, provided that the amplitude of the complex scalar is frozen modulo the… read more here.

DOI: 10.1109/tap.2017.2670607
Abstract: An upgraded adaptive cross approximation (U-ACA) algorithm in complex field is proposed, including detailed discussion about both relative-error estimator and pivoting threshold. Two new relative-error estimators are constructed, and the range of the pivoting threshold… read more here.
