Twenty-five questions for string theorists
In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in supersymmetric and string phenomenology. We describe each within the context of string constructions, illustrating them with specific examples where applicable. Each topic culminates in a set of questions that we believe...
متن کاملTASI Lectures: Cosmology for String Theorists
These notes provide a brief introduction to modern cosmology, focusing primarily on theoretical issues. Some attention is paid to aspects of potential interest to students of string theory, on both sides of the two-way street of cosmological constraints on string theory and stringy contributions to cosmology. Slightly updated version of lectures at the 1999 Theoretical Advanced Study Institute ...

1. Assume everything you know from the notes on Riemann-Stieltjes integration. (a) Show that if g : [0, 1]→ R is Riemann-integrable on [0, 1] and φ : [a, b]→ R is continuous on an interval [a, b] ⊇ g[[0, 1]], then φ ◦ g is Riemann-integrable on [0, 1]. (b) Assume that f : [0, 1]→ R is a function for which f ′(t) exists at each t ∈ [0, 1] (one-sidedly at endpoints) and that the Riemann integral ...

1. (a) Let (X, ‖ · ‖) and (Y, ‖ · ‖) be normed spaces. Show that the following conditions on a family T ⊆ L(X, Y ) are logically equivalent: (1) {‖T ‖ : T ∈ T} is bounded in R; (2) {T : T ∈ T} is equicontinuous at some point of X ; (3) {T : T ∈ T} is equicontinuous at 0 ∈ X ; (4) {T : T ∈ T} is equicontinuous at every point of X . (This order may not be the most efficient one to prove round-rob...
متن کاملFive Questions
I’ve always been torn between studying physics and studying computer science, but it was the theoretical aspects of both that attracted me the most. There’s clearly overlap in the computational physics arena, but I found that coming up with good numerical approximations to systems wasn’t really to my taste. It was only when I began studying information theory that I came to understand that ther...
