Operations between functions [PDF]
Communications in Analysis and Geometry, 2018 A structural theory of operations between real-valued (or extended-real-valued) functions on a nonempty subset A of Rn is initiated. It is shown, for example, that any operation ∗ on a cone of functions containing the constant functions, which is pointwise, positively homogeneous, monotonic, and associative, must be one of 40 explicitly given types.

Advances in Mathematics, 2004 We construct natural maps (the Klein and Wirtinger maps) from moduli spaces of vector bundles on an algebraic curve $X$ to affine spaces, as quotients of the nonabelian theta linear series. We prove a finiteness result for these maps over generalized Kummer varieties (moduli of torus bundles), leading us to conjecture that the maps are finite in ...

CLASSES OF OPERATOR-SMOOTH FUNCTIONS. I. OPERATOR-LIPSCHITZ FUNCTIONS [PDF]
Proceedings of the Edinburgh Mathematical Society, 2005 AbstractIn this paper we study the spaces of operator-Lipschitz functions and the spaces of functions closed to them: commutator bounded. Apart from the standard operator norm on $B(H)$, we consider a rich variety of symmetric operator norms and spaces of operator-Lipschitz functions with respect to these norms.

The function of auxiliary operators [PDF]
Molecular Microbiology, 1998 Gene regulation by control of transcription has been analysed in great detail both in prokaryotes and in eukaryotes. The frequency of transcription may be decreased by repressors or increased by activators. A repressor may work by decreasing the concentration of RNA polymerase at a promoter capable of forming an open complex.

Operations for D-Algebraic Functions
ACM Communications in Computer Algebra, 2023 A function is differentially algebraic (or simply D-algebraic) if there is a polynomial relationship between some of its derivatives and the indeterminate variable. Many functions in the sciences, such as Mathieu functions, the Weierstrass elliptic functions, and holonomic or D-finite functions are D-algebraic.

Epigraph of operator functions [PDF]
Quaestiones Mathematicae, 2016 It is known that a real function $f$ is convex if and only if the set $$\mathrm{E}(f)=\{(x,y)\in\mathbb{R}\times\mathbb{R};\ f(x)\leq y\},$$ the epigraph of $f$ is a convex set in $\mathbb{R}^2$. We state an extension of this result for operator convex functions and $C^*$-convex sets as well as operator log-convex functions and $C^*$-log-convex sets ...
