Weak crossed biproducts and weak projections [PDF]

open access: yesScience China Mathematics, 2012
We present the universal theory of weak crossed biproducts, and we prove that every weak projection of weak bialgebras induces an example of this crossed structure. As an example, we give the construction of a weak projection of a weak bialgebra associated to a groupoid that admits an exact factorization.

Improving the methodology of shooting the ball in the basket using exercises in asymmetrical direction in the movement of 12-14-year-old basketball players [PDF]

open access: yesBIO Web of Conferences
The basic use of exercises of an asymmetric orientation is to improve the methods of teaching throwing the ball into the basket in motion to basketball players 12-14 years old. In basketball, increased activity during the competition period, and even the

Robust Pulse-Pumped Quadratic Soliton Assisted by Third-Order Nonlinearity

open access: yesPhotonics, 2023
The generation of a quadratic soliton in a pulse-pumped microresonator has attracted significant interest in recent years. The strong second-order nonlinearity and high peak power of pumps offer a straightforward way to increase efficiency. In this case,

Local Regularity For Elliptic Systems With p, q-Growth

open access: yesBruno Pini Mathematical Analysis Seminar, 2015
In this paper we consider quasilinear elliptic systems with p, q-growth. We discuss some aspects of the theory of regularity for systems and we state a local boundedness result for weak solutions, obtained in collaboration with P. Marcellini. Moreover, a

WEAK SATURATION AND WEAK AMALGAMATION PROPERTY [PDF]

open access: yesThe Journal of Symbolic Logic, 2019
Abstract We study the two model-theoretic concepts of weak saturation and weak amalgamation property in the context of accessible categories. We relate these two concepts providing sufficient conditions for existence and uniqueness of weakly saturated objects of an accessible category ${\cal K}$ .

The Power of the Weak

open access: yesACM Transactions on Computational Logic, 2020
A landmark result in the study of logics for formal verification is Janin and Walukiewicz’s theorem, stating that the modal μ-calculus (μML) is equivalent modulo bisimilarity to standard monadic second-order logic (here abbreviated as SMSO) over the class of labelled transition systems (LTSs for short).
