Towards a Poetics of Stutter: Semantic and Syntactic Deconstruction in Saint John of the Cross and Stéphane Mallarmé
The present paper analyzes semantic and syntactic deconstruction in Saint John of the Cross and StĂ©phane MallarmĂ©, which is closely connected to the motif of stutter in both their works. It will be shown that, in each case, this motif describes language’s outlying district, an intermediate space between speech and silence, and an ongoing and simultaneous process of dissolution and manifestation that involves the poetic word on the one hand, and the transcendent signified (God in the case of Saint John, mainly the “Spirit” for MallarmĂ©) on the other.El presente trabajo analiza la deconstrucciĂłn semántica y sintáctica en la obra de san Juan de la Cruz y StĂ©phane MallarmĂ©, procedimiento lingĂĽĂstico que en ambos autores está relacionado con el motivo del balbucir. Se mostrará que, en ambos casos, este motivo describe una zona perifĂ©rica del lenguaje, un espacio intermedio e intermediario entre lenguaje y silencio, y un proceso continuo y simultáneo de disoluciĂłn y manifestaciĂłn que incluye, por un lado, la palabra poĂ©tica y, por otro, el significado transcendente (Dios, en el caso de san Juan de la Cruz, principalmente el “EspĂritu” en el caso de MallarmĂ©)
A Krylov subspace algorithm for evaluating the phi-functions appearing in exponential integrators
We develop an algorithm for computing the solution of a large system of
linear ordinary differential equations (ODEs) with polynomial inhomogeneity.
This is equivalent to computing the action of a certain matrix function on the
vector representing the initial condition. The matrix function is a linear
combination of the matrix exponential and other functions related to the
exponential (the so-called phi-functions). Such computations are the major
computational burden in the implementation of exponential integrators, which
can solve general ODEs. Our approach is to compute the action of the matrix
function by constructing a Krylov subspace using Arnoldi or Lanczos iteration
and projecting the function on this subspace. This is combined with
time-stepping to prevent the Krylov subspace from growing too large. The
algorithm is fully adaptive: it varies both the size of the time steps and the
dimension of the Krylov subspace to reach the required accuracy. We implement
this algorithm in the Matlab function phipm and we give instructions on how to
obtain and use this function. Various numerical experiments show that the phipm
function is often significantly more efficient than the state-of-the-art.Comment: 20 pages, 3 colour figures, code available from

Una mordedura misteriosa: la experiencia del otro en el «Cántico espiritual» de san Juan de la Cruz y «L’Après-midi d’un faune» de Stéphane Mallarmé
Como parte de un estudio comparado que pretende detectar elemen-tos de la teologĂa negativa en las obras de san Juan de la Cruz y StĂ©phane Mallar-mĂ©, el presente trabajo compara dos poemas en concreto, el «Cántico espiritual» y «L’Après-midi d’un faune», con vistas a la experiencia del otro
Capillary pressure of van der Waals liquid nanodrops
The dependence of the surface tension on a nanodrop radius is important for
the new-phase formation process. It is demonstrated that the famous Tolman
formula is not unique and the size-dependence of the surface tension can
distinct for different systems. The analysis is based on a relationship between
the surface tension and disjoining pressure in nanodrops. It is shown that the
van der Waals interactions do not affect the new-phase formation thermodynamics
since the effect of the disjoining pressure and size-dependent component of the
surface tension cancel each other.Comment: The paper is dedicated to the 80th anniversary of A.I. Rusano
