Многомерни операционни смятания за нелокални гранични задачи за еволюционни уравнения
, 2011 [Dimovski Ivan H.; Димовски Иван Х.]; [Tsankov Yulian Ts.; Цанков Юлиан Ц.]Here we propose a direct operational calculus approach to nonlocal boundary value problems for a large class of linear evolution equations with several space variables and one ...

, 2011 In this paper continuity of the Bessel wavelet transform B ψ of function φ in terms of a mother wavelet ψ is investigated on certain distribution spaces when the Hankel transform of ψ defined by ψ(x, y) ∈ C ∞ (R 2 + ).

Connections between classical and generalised trajectories of a state/signal system
, 2020 . In our earlier article "Well-posed state/signal systems in continuous time", we originally defined the notion of a trajectory of a state/signal system by means of a generating subspace.

Точно решение на задачата на Бицадзе-Самарски
, 2010 Иван Димовски, Юлиан Цанков - В статията е намерено точно решение на задачата на Бицадзе-Самрски (1) за уравнението на Лаплас, като е използвано операционно смятане основано на некласическа двумернa конволюция. На това точно решение може да се гледа като

, 1998 Based on a new definition of dilation a scale discrete version of spherical multiresolution is described, starting from a scale discrete wavelet transform on the sphere. Depending on the type of application, different families of wavelets are chosen.

, 1996 We show that the singular values oe m of the fractional integration operator of order ff ? 0 acting from weighted L 2 spaces of functions defined on the interval (\Gamma1; 1) or (0; 1) may, in both cases, have asymptotics m \Gammaff or m \Gammaff=2 ,

On the Inversion of the Convolution and Laplace Transform
, 2007 We present a new inversion formula for the classical, finite, and asymptotic Laplace transform f of continuous or generalized functions f . The inversion is given as a limit of a sequence of finite linear combinations of exponential functions whose ...
