Science education in context: An overview and some observations [PDF]

, 2008
This book presents an international perspective of the influence of educational context on science education. By this we mean the context in which the teaching and learning takes place, rather than the use of a context-based approach to learning and ...

Critical exponents of the

, 2002
The critical exponents of the classical spin glasses with $O(m-2n)\otimes U(n)$ symmetry are obtained to order $\epsilon^2$ of the ϵ-expansion around six dimensions, where $\epsilon =6-d$. This new unitary symmetry is realized in the m-vector ($m\geq 2$)

Continuously Varying Critical Exponents Beyond Weak Universality

, 2017
Renormalization group theory does not restrict the form of continuous variation of critical exponents which occurs in presence of a marginal operator.

Critical exponents of graphs

, 2016
The study of entrywise powers of matrices was originated by Loewner in the pursuit of the Bieberbach conjecture. Since the work of FitzGerald and Horn (1977), it is known that is positive semidefinite for every entrywise nonnegative positive ...

Critical Design in Context: History, Theory and Practices (Second Edition)

Critical Design moves away from traditional approaches that limit design's role to the production of profitable objects, focusing instead on a practice that is interrogative, discursive and experimental.

On some nonlinear PDEs with Sobolev-hardy critical exponents and a Li-Lin open problem

, 2015
Let Ω be a C1 open bounded domain in RN, N ≥ 3, with (Formula presented.). We consider the following problem involving Hardy–Sobolev critical exponents: (Formula presented.), where 0 ≤ s1 < 2, 0 ≤ s2 < 2, 2 *(s2) ≠ λ ∈ R, 1 ≤ p ≤ 2*(s1) - 1 and with ...

Critical exponents of balanced words

, 2018
Over a binary alphabet it is well-known that the aperiodic balanced words are exactly the Sturmian words. The repetitions in Sturmian words are well-understood.
