Computing in matrix groups without memory [PDF]

open access: yes, 2013
Funding: UK Engineering and Physical Sciences Research Council award EP/K033956/1Memoryless computation is a novel means of computing any function of a set of registers by updating one register at a time while using no memory.

A note on continuity of semigroups of maps [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
An example is given of a separately continuous semigroup of transformations on Hilbert space which fails to be jointly continuous at t = 0

Spectral mapping theorems for differentiable $$C_0$$ semigroups [PDF]

open access: yesRendiconti del Circolo Matematico di Palermo Series 2, 2020
Let $(T(t))_{t\geq 0}$ be a $C_0$ semigroup on a Banach space $X$ with infinitesimal generator $A$. In this work, we give conditions for which the spectral mapping theorem $σ_{*}(T(t))\backslash \{0\}=\{e^{λs}, λ\inσ_{*}(A)\}$ holds, where $σ_*$ can be equal to the essential, Browder and Kato spectrum.

Nonlinear ergodic theorems for asymptotically almost nonexpansive curves in a Hilbert space

open access: yesAbstract and Applied Analysis, 2000
We introduce the notion of asymptotically almost nonexpansive curves which include almost-orbits of commutative semigroups of asymptotically nonexpansive type mappings and study the asymptotic behavior and prove nonlinear ergodic theorems for such curves.

A note on Kakutani type fixed point theorems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We present Kakutani type fixed point theorems for certain semigroups of self maps by relaxing conditions on the underlying set, family of self maps, and the mappings themselves in a locally convex space setting.

On the Structure of the Semigroup of Entire Étale Mappings [PDF]

open access: yesComplex Analysis and Operator Theory, 2013
We hope to be able (in the future) to carefully analyze this structure and to tie the Jacobian Conjecture in dimension two to certain Zeta functions, thereby invoking a powerful arithmetic machinery to handle the two dimensional Jacobian Conjecture. Let us denote by ${\rm et}(\mathbb{C}^2)$ the semigroup of two dimensional Keller mappings.

A General Class of Differential Hemivariational Inequalities Systems in Reflexive Banach Spaces

open access: yesMathematics, 2021
We consider an abstract system consisting of the parabolic-type system of hemivariational inequalities (SHVI) along with the nonlinear system of evolution equations in the frame of the evolution triple of product spaces, which is called a system of ...

On the semigroups of Fredholm mappings [PDF]

open access: yesJournal of the Australian Mathematical Society, 1972
LetE1andE2be real Banach spaces and letL(E1) andL(E2) be the Banach algebras of all continuous linear mappings onE1andE2respectively. It is a well- known result of M. Eidelheit [1] thatL(E1) thatL(E2) are isomorphic as rings if and only ifE1andE2are topologically and algebraically isomorphic.
