Online Material: Additional site maps, plots and correlation fits. The recent 2011 M w 9.0 Tohoku, Japan, and the 2004 M w 9.15 Sumatra–Andaman superquakes have humbled many in earthquake research. Neither region was thought capable of earthquakes exceeding M w∼8.4.

SUPERCYCLICITY OF JOINT ISOMETRIES [PDF]
Bulletin of the Korean Mathematical Society, 2015 Abstract. Let H be a separable complex Hilbert space. A commut-ing tuple T = (T 1 ,...,T n ) of bounded linear operators on H is called aspherical isometry ifP ni=1 T ∗i T i = I. The tuple T is called a toral isom-etry if each T i is an isometry. In this paper, we show that for each n≥1there is a supercyclic n-tuple of spherical isometries on C n and ...

Rotations of Hypercyclic and Supercyclic Operators
Integral Equations and Operator Theory, 2004A (bounded linear) operator \(T\) on a Banach space \(X\) is called hypercyclic if there is a vector \(x \in X\) such that its orbit \(\{T^n(x) \;| \;n=0,1,2,... \}\) is dense in \(X\); the vector \(x\) is called hypercyclic for \(T\). The operator \(T\) is called supercyclic if \(\{ \alpha T^n(x) \;| \alpha \in \mathbb C, n \in \mathbb N \}\) is dense

The Conjugate Class of a Supercyclic Operator
Complex Analysis and Operator Theory, 2011The authors show that the conjugate class of any supercyclic operator \(T\) on a separable, infinite dimensional real or complex Banach space \(X\) contains a path of supercyclic operators which is dense in the strong operator topology. For the case when \(X\) is a complex Banach space, the authors prove that the set of common supercyclic vectors for ...

If \(T\) is an operator on a Hilbert space \(H\) and \(x \in H\), the orbit of \(x\) under \(T\) is \(O(x,T):=\{T^n(x) : n \in \mathbb{N} \}\) and the scaled orbit of \(T\) is the set \(S(x,T):=\{c T^n(x) : c \in \mathbb{K}, \;n \in \mathbb{N} \}\); here, \(\mathbb{K}\) is the field of real or complex numbers. An operator \(T\) on a Hilbert space \(H\)

On weak positive supercyclicity
Israel Journal of Mathematics, 2008Let \(X\) be a complex topological vector space and let \({\mathcal M}'\) be the commutant of a semigroup \({\mathcal M}\) of continuous linear operators on \(X\). The main result of this paper states that if there is an operator \(T\in{\mathcal M}\cap{\mathcal M}'\) which is not a multiple of the identity and for which \(p(T)\) has dense range for all

Low power supercycled TPPM decoupling
Journal of Magnetic ResonanceImproving the spectral sensitivity and resolution of biological solids is one of the long-standing problems in nuclear magnetic resonance (NMR) spectroscopy. In this report, we introduce low-power supercycled variants of two-pulse phase-modulated (TPPM) sequence for heteronuclear decoupling.
