The bounded complexity function versus the unbounded complexity function

open access: yesJournal of Mathematical Analysis and Applications, 2012
Abstract We construct two point-wise periodic flows which are equivalent, such that all the complexity functions of one flow are bounded while the other flow has an unbounded complexity function.

On the Trigonometric and p-Trigonometric Functions of Elliptical Complex Variables

open access: yesCommunications in Advanced Mathematical Sciences, 2020
In the early 2000s, the geometry of a one-parameter family of generalized complex number systems was studied (Math. Mag. 77(2)(2004)). This family is denoted by Cp.

Charge distribution functions for characterization of complex systems

open access: yesХімія, фізика та технологія поверхні, 2021
A set of characteristics calculated within the scope of quantum chemistry methods may be assigned to local ones changing from atom to atom in complex systems. Simple averaging of the related values gives rather poor characteristics of the systems because

Complex pectin metabolism by gut bacteria reveals novel catalytic functions

open access: yesNature, 2017
The metabolism of carbohydrate polymers drives microbial diversity in the human gut microbiota. It is unclear, however, whether bacterial consortia or single organisms are required to depolymerize highly complex glycans.

On subword complexity functions

open access: yesDiscrete Applied Mathematics, 1984
The author finds a polynomial formula for the subword complexity function of a cyclic language. A characterization of context-free languages with exponential subword complexity is derived by appropriately using the pumping lemma.

On the complexity of slice functions

open access: yesTheoretical Computer Science, 1985
By results of Razborov negations can be very powerful for Boolean circuits. But for the class of slice functions negations are almost powerless. Hence each hard function has a hard slice. Lower bounds on the monotone circuit complexity of slice functions imply lower bounds on the circuit complexity of these functions.

On the Complexity of Real Functions [PDF]

open access: yes46th Annual IEEE Symposium on Foundations of Computer Science (FOCS'05), 2005
We develop a notion of computability and complexity of functions over the reals, which seems to be very natural when one tries to determine just how "difficult" a certain function is. This notion can be viewed as an extension of both BSS computability [Blum, Cucker, Shub, Smale 1998], and bit computability in the tradition of computable analysis ...

Convolution powers of complex functions on Z [PDF]

open access: yes, 2012
Repeated convolution of a probability measure on Z leads to the central limit theorem and other limit theorems. This paper investigates what kinds of results remain without positivity. It reviews theorems due to Schoenberg, Greville, and Thomée which are
