A fundamental solution to the CCC equations [PDF]
We display a simple solution to the Penrose CCC scenario. For this solution we chose for the late stages of the previous aeon a FRW, k=0, universe with a both a cosmological constant and radiation (no mass) while for the early stages of the 'present' aeon we have again a FRW universe, k=0, with the same cosmological constant and again with radiation ...

Supersymmetry, Duality and Bound States [PDF]
$P$-brane solutions of low-energy string actions have traditionally provided the first evidence for the existence of string dualities, in which fundamental and solitonic $p$-branes are identified with perturbative and non-perturbative BPS states. In this

Fundamental solutions for the new coupled Konno-Oono equation in magnetic field
We implement an efficient solver to retrieve solutions to the nonlinear new coupled Konno–Oono (CKO) equation. This solver presents the closed form of solutions.

Transport in nanopores and nanochannels: some fundamental challenges and nature-inspired solutions
The field of solid-state nanopores and nanochannels has grown exponentially in the past five years. Recent advances have greatly broadened the spectrum of available gating stimuli, expanded applications in sensing, energy conversion, and separation ...

We search for tubular solutions in unstable D3-brane. With critical electric field E=1, solutions representing supertubes, which are supersymmetric bound states of fundamental strings, D0-branes, and a cylindrical D2-brane, are found and shown to exhibit

Fundamental solutions for the Tricomi operator, II [PDF]
We explicitly calculate fundamental solutions for the Tricomi operator relative to a point in the hyperbolic region and show that these solutions originate from the hypergeometric function F(1/6,1/6;1;z).

The Dirichlet problem for the generalized bi-axially symmetric Helmholtz equation [PDF]
In [18], fundamental solutions for the generalized bi-axially symmetric Helmholtz equation were constructed in $R_2^ + = \left\{ {\left( {x,y} \right):x > 0,y > 0} \right\}.$ They contain Kummer's confluent hypergeometric functions in three variables. In

On Fundamental Solutions of Elliptic Equations [PDF]
In this paper we prove: Let L be an elliptic operator in (x, t) with constant coefficients, the coefficients of the lower derivatives being zero, and let Lo be the operator obtained from L by deleting all the terms involving t-derivatives. Let K(x, t) be a fundamental solution of Lu = 0.
