Functional calculus for a class of unbounded linear operators on some non-archimedean Banach spaces [PDF]
, 2005 summary:This paper is mainly concerned with extensions of the so-called Vishik functional calculus for analytic bounded linear operators to a class of unbounded linear operators on $c_0$.

Journal of Mathematical Analysis and Applications, 1989 Making use of fractional calculus, the authors define a certain linear operator \(\Lambda\) (\(\lambda)\) (\(\lambda\neq 1,2,3,...)\) on the class \({\mathcal A}\) of (normalized) analytic functions f(z) in the open unit disk \({\mathcal U}=\{z:\) \(| z|

Symbolic Analysis for Boundary Problems: From Rewriting to Parametrized Groebner Bases [PDF]
, 2010 We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras.

Continuity of homomorphisms and derivations from algebras of approximable and nuclear operators [PDF]
, 1994 1. Let be a Banach algebra. We say that homomorphisms from are continuous if every homomorphism from into a Banach algebra is automatically continuous, and that derivations from are continuous if every derivation from into a Banach -bimodule is ...

A functional calculus and fractional powers for multivalued linear operators
Osaka Journal of Mathematics, 2000 This is a continuation of the earlier work of the two first authors [Potential Analysis Theory 9, No. 4, 301-319 (1998; Zbl 0927.47011)]. The authors improve a functional calculus valid for a wider class of functions. By applying the functional calculus a theory of fractional powers for multivalued nonnegative linear operators is obtained.

International Journal of Analysis and Applications, 2015 Let X and Y two complex Banach spaces and (A,B) a pair of bounded linear operators acting on X with value on Y. This paper is concerned with spectral analysis ofthe pair (A;B): We establish some properties concerning the spectrum of the linear operator

Fractional calculus of periodic distributions
, 2011 Two approaches for defining fractional derivatives of periodic distributions are presented. The first is a distributional version of the Weyl fractional derivative in which a derivative of arbitrary order of a periodic distribution is defined via Fourier

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
