On the adjoint of a symmetric operator [PDF]
In general it is a non-trivial task to determine the adjoint S* of an unbounded symmetric operator S in a Hilbert or Krein space. We propose a method to specify S* explicitly which makes use of two boundary mappings that satisfy an abstract Green's ...

Modelling uncertainty for flash floods in coastal plains using adjoint methods [PDF]
This paper shows the application of adjoint sensitivity analysis to flash flood wave propagation in a river channel. The adjoint sensitivity analysis is used to assess flood hazard in a coastal area caused by river discharge.

Triple Operators of Order n on a Hilbert Space
In this paper, we introduce a new class of operators on a complex Hilbert space which is called triple operators of order n. An operator is called triple operator of order n if where is the adjoint of the operator .

Ding–Iohara–Miki symmetry of network matrix models
Ward identities in the most general “network matrix model” from [1] can be described in terms of the Ding–Iohara–Miki algebras (DIM). This confirms an expectation that such algebras and their various limits/reductions are the relevant substitutes ...

Higher spin currents in the orthogonal coset theory
In the coset model $$(D_N^{(1)} \oplus D_N^{(1)},D_N^{(1)})$$ ( D N ( 1 ) ⊕ D N ( 1 ) , D N ( 1 ) ) at levels $$(k_1,k_2)$$ ( k 1 , k 2 ) , the higher spin 4 current that contains the quartic WZW currents contracted with a completely symmetric SO(2N ...

Integrable three-dimensional coupled nonlinear dynamical systems related with centrally extended operator Lie algebras [PDF]
A hierarchy of Lax-type flows on a dual space to the centrally extended Lie algebra of integral-differential operators with matrix-valued coefficients is considered.

Premature deaths attributed to source-specific BC emissions in six urban US regions
Recent studies have shown that exposure to particulate black carbon (BC) has significant adverse health effects and may be more detrimental to human health than exposure to PM _2.5 as a whole.
