A New Extended Cosine—G Distributions for Lifetime Studies
Mathematics, 2021 In this article, we introduce a new extended cosine family of distributions. Some important mathematical and statistical properties are studied, including asymptotic results, a quantile function, series representation of the cumulative distribution and ...

Cosine families in GDP Quojection-Fréchet spaces
Boletim da Sociedade Paranaense de Matemática, 2022 We prove that if the Quojection-Fréchet space $X$ is a Grothendieck space with the Dunford-Pettis property, then every $C_ {0}$-cosine family is necessarily uniformly continuous and therefore its infinitesimal generator is a continuous linear operator.

ON COSINE FAMILIES CLOSE TO SCALAR COSINE FAMILIES [PDF]
Journal of the Australian Mathematical Society, 2015 We prove that if two normed-algebra-valued cosine families indexed by a single Abelian group, of which one is bounded and comprised solely of scalar elements of the underlying algebra, differ in norm by less than$1$uniformly in the parametrising index, then these families coincide.

Mild and classical solutions to a fractional singular second order evolution problem
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Existence and uniqueness of mild and classical solutions are discussed for an abstract second-order evolution problem. The nonlinearity contains a local term and a non-local term.

The Growth-Rate of Cosine Families
Journal of Mathematical Analysis and Applications, 1995 The authors study the growth rate of a cosine family of operators generated by a linear operator \(A\) in terms of the resolvent of \(A\) and the semigroup generated by \(A\).

Performance Evaluation of Raised-Cosine Wavelet for Multicarrier Applications [PDF]
, 2014 YesWavelets are alternative building kernels of the multicarrier systems, such as the orthogonal frequency division multiplexing (OFDM). The wavelets can be designed by changing the parent basis functions or constructing new filters.

On a second-order differential problem with fractional derivatives of order greater than one
Mathematical Modelling and Analysis, 2013 A second-order abstract problem with derivatives of non-integer order is investigated. The nonlinearity involves fractional derivatives between 1 and 2. Existence and uniqueness of mild and classical solutions are established in appropriate spaces.

Some properties of set-valued sine families [PDF]
Opuscula Mathematica, 2012 Let \(\{F_t : t \geq 0\}\) be a family of continuous additive set-valued functions defined on a convex cone \(K\) in a normed linear space \(X\) with nonempty convex compact values in \(X\). It is shown that (under some assumptions) a regular sine family
