Semi-analytical approximation of the normal derivative of the heat simple layer potential near the boundary of a two-dimensional domain [PDF]
A semi-analytical approximation of the normal derivative of the simple layer heat potential near the boundary of a two-dimensional domain with $C^{5} $ smoothness is proposed.

Factorization of Numbers with the temporal Talbot effect: Optical implementation by a sequence of shaped ultrashort pulses [PDF]
We report on the successful operation of an analogue computer designed to factor numbers. Our device relies solely on the interference of classical light and brings together the field of ultrashort laser pulses with number theory.

On Tractable Exponential Sums [PDF]
We consider the problem of evaluating certain exponential sums. These sums take the form $\sum_{x_1,...,x_n \in Z_N} e^{f(x_1,...,x_n) {2 \pi i / N}} $, where each x_i is summed over a ring Z_N, and f(x_1,...,x_n) is a multivariate polynomial with ...

Factorization of numbers with Gauss sums: I. Mathematical background
We use the periodicity properties of generalized Gauss sums to factor numbers. Moreover, we derive rules for finding the factors and illustrate this factorization scheme for various examples.

A Kronecker-type identity and the representations of a number as a sum of three squares [PDF]
By considering a limiting case of a Kronecker-type identity, we obtain an identity found by both Andrews and Crandall. We then use the Andrews-Crandall identity to give a new proof of a formula of Gauss for the representations of a number as a sum of ...

On the mean value of dedekind sum weighted by the quadratic gauss sum [PDF]
Let \(p\) be the prime greater than \(3\) and such that \(p\equiv 3 \mod 4\). The authors prove three identities. Among them the most important is \[ h_p^2=\frac {(p-1)(p-2)}6-\sum _{m=1}^{p-1}G(m^2-1,\chi _0;p)S(c^2,p), \] where \(h_p\), \(G(m,\chi ;q)\) and \(S(h,q)\) is the class number of the quadratic field \(\mathbb Q(\sqrt {-p})\), the quadratic

Lattices with many Borcherds products [PDF]
We prove that there are only finitely many isometry classes of even lattices $L$ of signature $(2,n)$ for which the space of cusp forms of weight $1+n/2$ for the Weil representation of the discriminant group of $L$ is trivial.

The value distribution of incomplete Gauss sums
It is well known that the classical Gauss sum, normalized by the square-root number of terms, takes only finitely many values. If one restricts the range of summation to a subinterval, a much richer structure emerges.

The classification of 2-connected 7-manifolds [PDF]
We present a classification theorem for closed smooth spin 2-connected 7-manifolds M. This builds on the almost-smooth classification from the first author's thesis.
