Spectral Stability of NBBD under Sparse Zero Tolerance: A Probabilistic Coercivity Framework

We present a reproducible analytic framework for NBBD completeness under sparse zerotolerance. By introducing a probabilistic mean-oscillation space X′, we establish A2 control forthe weight w = e2F , where F = log |U(σ + it)|. This ensures coercivity of the Mellin-HilbertGram operator T00, and spectral stability near the critical line.

A Structural Framework for the Riemann Hypothesis via Coercivity and Surrogate Stability

We present a falsifiable analytic structure for the Riemann Hypothesis based on the coercivityof a Mellin-Hilbert Gram operator. This framework is structurally coherent and empiricallystable. It does not claim logical completeness or final proof, but offers a recurrence-resistantflow formalized within ZFC and supported by surrogate estimates.

Phosfhonate ligands stabilize mixed-valent ((Mn20-xMnxII)-Mn-III} clusters with large spin and coercivity

2005
The mixed-valent {MnIII20−xMnIIx} cage complexes (x=2–6) have structures corresponding to a fragment of a cubic close-packed lattice (see picture, Mn large sphere, O small sphere). Magnetic studies show for the cage with x=2 that the ground state has a spin (S) of 19±1 in low field, which increases to about S=30 at higher fields.

Analytic Coercivity Framework for the Riemann Hypothesis: Gamma-Core Operator Stability and Outer Factor Continuity

We present an operator-theoretic framework related to the Riemann Hypothesis (RH), built on aMellin-type convolution operator Tσ on L2(wσ) with wσ(t) = |ζ(σ + it)|2. The analysis combines(i) a Gamma core–tail decomposition with quantitative Stirling bounds and conservative Gammaapproximation errors EΓ(σ, ξ0), (ii) principal symbol positivity with phase
